This category deals with the polychora with trapezoid pyramid (trapyr for short) vertex figures along with their regiments. There are 30 regiments of 3. Prismatorhombates can also be called prismatotruncates and are also called cantetruncates (Norman Johnson), they have xoxx type symbols. There are other trapyr-verted polytopes mentioned here also that are not technically "prismatorhombates", but they do have similar verfs. Convex ones are prip, prit, proh, prico, prahi, and prix. They are all tame. The first two of each regiment are orientable, while the last one is non. Prip is the only pentachoric regiment, its members have 60 vertices. Prit, Proh, Quiproh, and Gichado regiments have tessic symmetry and these polychora have 192 vertices. Prico, Suti, Ditdi, and Gipti regiments have icoic symmetry with 576 vertices. All others have 7200 vertices with hyic symmetry. The regiments can be subdivided into the following groups: Convex (prip-prix), Starry (pirshi-pirgaghi), Quippirs (quiproh-quippirgax), Paquers (gichado-gippixady), Cotcoic (suti-sixathi) and Ditrigonal (gid tipathi-sphiddix).
