The stericantic 6-cube, also called the runcitruncated 6-demicube, prismatotruncatodemihexeract, or pithax, is a convex uniform 6-polytope. It consists of 12 stericantic 5-cubes, 32 bicantellated 5-simplices, 32 runcitruncated 5-simplices, and 160 triangular-truncated tetrahedral duoprisms. 2 stericantic 5-cubes, 1 bicantellated 5-simplex, 2 runcitruncated 5-simplices, and 2 triangular-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the runcitruncation of the 6-demicube.
Vertex coordinates[edit | edit source]
The coordinates of a stericantic 6-cube, centered at the origin and with unit edge length, are given by all permutations and even sign changes of:
- .
Representations[edit | edit source]
A stericantic 6-cube has the following Coxeter diagrams:
- x3x3o3x3o *b3o () (full symmetry)
- s4o3x3o3x3o () (as alternated stericantellated 6-cube)
