Prismatorhombated heptapeton

The prismatorhombated heptapeton or pril, also called the runcicantellated heptapeton or runcicantellated 6-simplex, is a convex uniform polypeton. It consists of 7 prismatorhombated hexatera, 7 bitruncated hexatera, 21 truncated pentachoric prisms, and 35 triangular-tetrahedral duoprisms. 3 prismatorhombated hexatera, 1 bitruncated hexateron, 2 truncated pentachoric prisms, and 1 triangular-tetrahedral duoprism join at each vertex. As the name suggests, it is the runcicantellation of the heptapeton.
