Uniform Polypeta and Other Six Dimensional Shapes

Welcome to the all new polypeton web site. This web site will focus on the uniform polytopes of six dimensions. This count is still underway and I hope to have all of the typical ones enumerated soon. The main symmetries are hoppic (simplex), axic (hexeract), haxic (demihexeract), and jakic (E6 polytope Jak). Hoppic and jakic can be doubled to get feic and moic symmetry. All of the typical hoppics (includes feics) are now counted, there are 916 of them. So far only the largest regiments have yet to be counted of the other symmetries and the total count is already breaking 10,328 - which only includes the fully counted and defissed non-prismattic regiments! Chosidap was discovered Dec. 16, 2016 along with higher dimensional versions of hosiap. In October 2019, I found 135 new members in the hax regiment along with new compounds and fissaries there, increasing its size by an order of magnitude. Below is a breakdown of the count along with uncounted regiments listed after them:

Hopic - 916

Axic - 5832 - brox, brag, spog, siborg, sobpoxog, gipkix, sipkix

Haxic - 1268 - sophax

Jakic - 2291 - rojak, ram, sirjak, shopjak, spojak, spam, sabrim

Misc - 21

Definition of Uniform Polypeton

A polypeton is uniform if its vertices are transitive (all alike in an isogonal sort of way) and all of it's facets (called petons) are uniform polytera.

A polypeton is a six dimensional polytope, where a polytope must be monal, dyadic, and properly connected. Monal means that every element is represented only once (two vertices cant be in the same place), dyadic means that if you take an n dimensional element and an n-2 dimensional element, then there are either 0 or 2 n-1 dimensional elements adjacent to both (in other words, edges have two vertices, only two facets meet at a ridge, and this is true for all of it's elements and element-figures (vertex figure and the like)). Properly connected means that it nor any of it's elements or element-figures are compounds (even though the compound of 5 cubes can act as a cell, it is actually five cells which are cubes). Properly connected also means that if any two n dimensional elements are in the same n space, then all of their common elements together must be limited to an n-1 dimensional space (in other words, if two cells are in the same realm, they are not rigidly locked together by common elements, like an ike-gad combo would be (ike and gad would share all 30 edges which is a 3-D arrangement instead of a 2-D or less arrangement, this ike-gad combo causes the object to be a coinciding case). Now consider 5 cubes in the same realm (like in the 5-cube compound), if you take any two of the cubes, they have no element in common (well technically they share the -1 dimensional nulloid in common which is sometimes called the empty polytope) - so therefore they are not rigidly locked like the ike-gad case. I decided to relax this restriction to allow the compound of 3 tesseracts (gico) to show up as a combo-facet, for it would of been rigidly locked, two tesses share 8 vertices in common which are arranged like the vertices of hex. My new version of this restriction would be that any n-facet regiment can only be activated once by either a true polytope or a pure compound in the regiment (as a combofacet), or a fissary if they are included in the count. This means that if the facet regiment is ico, then the compound gico is allowed - but the ico-gico combo is not since it will activate the ico regiment twice instead of once.

There are also a few non-uniform scaliform polypeta known, but the search for these has yet to be underway.

Basic Six Dimensional Shapes

These seven shapes can be considered as the basic 6-D shapes, they are either flat in each dimension or they join them in a uniform curve. The seven shapes are:

Hexeract - which can be generalized as a variety of hexablocks when the dimensions are of different length. This shape would be the basic building block in six dimensional space. It could be represented by ||||||.

Pentinder - This is the cross product of a disk and a tesseract. It has 8 tessinders as sides and one curved side. It is flat in four dimensions, the other two form a curve and it has rollability of 1. It could be represented as ||||().

Ducyclosquare - This is the cross product of the duocylinder and a square, also the cross product of two cylinders. It has four flat sides and two curved sides with rollability of 1. It could be represented as ||()().

Triocylinder - This is the cross product of three disks. It has three curved sides with rollability of 1. It could be represented as ()()().

Sphericube - It has three flat dimensions and three curved ones. It has rollability of 2 on curved side. This is the cross product of the sphere and a cube. It could roll like a ball on its curved side and it has six flat sides. It could be represented as |||(|).

Cylindisphere - It has one flat dimension and two that curve in a cycle and three that curve in a ball. It has rollability of 2 on one of the curved sides, and rollability of one on the other. This is the cross product of the sphere and a cylinder. It has two flat sides. It could be represented as |()(|).

Duospherinder - It has six curved dimensions. It has rollability of 2 on both curved sides. This is the cross product of two spheres. It could roll like a ball no matter how it is set. It could be represented as (|)(|).

Glomosquare - It has two flat dimensions and four curved ones. It has rollability of 3 on the curved side. This is the cross product of the glome and a square. It could roll like a glome on the curved side and set flat on four sides. It could be represented as ||(||).

Cycloglome - It has two dimension that curve in a cycle and four that curve in a glome. It has rollability of 1 and 3 depending on which of the two sides it sits on. This is the cross product of the glome and a circle. It could roll like a glome and like a circle. It could be represented as ()(||).

Pentorbinder - It has one flat dimension and five curved ones. It has rollability of 4 on the curved side. This is the prism of the pentorb and may be the can shape of 6 dimensions. It could roll like a pentorb. It could be represented as |(|||).

Hexorb - This is the six dimensional sphere, can also be called hexasphere. It has rollability of 6, for all six dimensions are curved. It could be represented as (||||).

Uniform Polypeton Categories

Currently I'm searching out the uniform polypeta and hope to completely enumerate the typical ones and find as many atypical ones as possible. Over 8000 uniform polypeta are currently known and I suspect the final count of the typical non-prismatic uniforms (typicals are those that are not snubs, swirlprisms, or other weird sort) will be a five digit number. Known atypical cases include those like iquipadah and those from category 38 and there are likely many others that are waiting to be found, could there be something like the idcossids but with jak or mo symmetry? - who knows! The Wythoffian regiments (categories 1-37) have symbols of the following forms where any of the o's can be either an o or an x and the x's stay as is: oooooo (hoppics), ooo8o (haxics), ooooo'o (axics), oooox"x (star axics), ooo(o'x"x) (blocky goccoics), oo(o'x"x)o (medial blocky goccoics), o(o'x"x)oo (medial spiky goccoics), (o'x"x)ooo (spiky goccoics), and oo8oo (jakics).

Here is a list of the 38 categories plus the 8 prismattic categories.

Category A: Prisms - There are 1292 prisms - a prism for every non-prismatic uniform polyteron (excluding the penteract which leads to the hexeract), their verfs are pyramids of the polyteron's verf.

Category B: Chorigonal Duoprisms - For all of the non-prismatic uniform polychora (1774 so far), there is an infinite set of "chorigonal" duoprisms. Their verfs are dyad disphenoids of the verf of the polychoron component.

Category C: Hedral Duoprisms - This set contains 2849 polyhedron-polyhedron duoprisms. They are the cross products AxB, where A and B are uniform polyhedra. Their verfs are X-Y disphenoids, where X and Y are the verfs of A and B.

Category D: Hedrigonal Dippips - This infinite set are simply the prisms of polyteron category B. The verfs disphenoid pyramids of the polyhedron verfs.

Category E: Hedral Antiprism Duoprisms - This infinite set are the cross product of the 3-D antiprisms and the uniform polyhedra. Their verfs are a-b dispheonids where a is the verf of an antiprism and b is the verf of a uniform polyhedron.

Category F: Antiprism Duoprisms - This infinite set are the cross product of two 3-D antiprisms. Their verfs are trapezoid-trapezoid disphenoids and their crossed versions.

Category G: Antiprismigonal Dippips - This infinite set are the prisms of polyteron castegory C. Their verfs are disphenoid pyramids of trapezoids and their crossed versions.

Following is a list of some of my other polytope related pages.

Home Page - This is my home page, it has links to some of my non-polytope pages such as Array Notation, Infinity Scrapers, Elements, Existence of God, etc.

Polyteron of the Day - Here are cross sections of many uniform polytera, a sort of warm up for the future of this webpage.

Polytwisters - This page lists the 194 known uniform polytwisters with pics of many of them (and many more pics to come). Polytwisters are like rollable twisted "polyhedra" in 4 dimensions. They dont have vertices, they have equators (rings). Their sides aren't flat like polyhedra, they are cylindrical. If placed on a 4-D table, it could roll no matter which way you set it.

Uniform Polychora - This web site deals with the four dimensional stuff.

Polytopes of Various Dimensions - This page lists the names of what polytopes are called in various dimensions, all the way up to a tridecillion dimensions! Example: in 10-D they are called polyxenna.

Dice of the Dimensions - This page describes the fair dice of variant dimensions, including those with curved sides.

Regiments - Here's something we've all been waiting for, a list of the various regiments with their members listed as well. I'm working on up the dimensions (at dimension 6 at the moment) and hope to get to dimension 8.

Special thanks to Andrew Weimholt, who has let me use his polytope.net domain to house my website. Without the domain there wouldn't of been enough room on my site to store all the pics.
