Biprismatorhombated heptapeton

The biprismatorhombated heptapeton or biruncitruncated heptapeton, also called the biruncitruncated 6-simplex, is a convex uniform polypeton. 2 prismatorhombated hexatera, 2 prismatotruncated hexatera, 1 triangular-octahedral duoprism, and 2 triangular-truncated tetrahedral duoprisms join at each vertex. As the name suggests, it is the biruncitruncation of the heptapeton.
