Category 10: Greater Truncates

There are 26 greater truncates, they include the great rhombates (ooxxx cases), great birhombates (oxxxo cases), great prismates (oxxxx cases) and the omnitruncates (xxxxx cases) along with those with similar verfs. All of these are tame and only grahehad is non-orientable. The gart regiment has two members, the others have one, I call one member regiments "lone operatives".

Great Rhombates

Great Rhombate Verfs

These seven have verfs shaped like regular polygon (or faceting) scalenes (aka polygon pyramid pyramids). All of them have pentic symmetry except for garx which has hixic symmetry. Garx has 120 vertices. Gart and grahehad which form a regiment has 480 vertices, the others have 640. The first three are convex. Above are the verfs as a series of cross sections.
