Celliprismatotruncated heptapeton

The celliprismatotruncated heptapeton or captal, also called the steriruncitruncated heptapeton or steriruncitruncated 6-simplex, is a convex uniform polypeton. It consists of 7 celliprismatotruncatododecatera, 7 prismatorhombated hexatera, 21 decachoric prisms, 35 triangular-truncated tetrahedral duoprisms, and 35 hexagonal-truncated tetrahedral duoprisms. 2 celliprismatotruncatododecatera, 1 prismatorhombated hexateron, 1 decachoric prism, 1 triangular-truncated tetrahedral duoprism, and 2 hexagonal-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the steriruncitruncation of the heptapeton.
