Teriprismated heptapeton

The teriprismated heptapeton or topal, also called the penticantellated heptapeton or penticantellated 6-simplex, is a convex uniform polypeton. It consists of 7 small rhombated hexatera, 7 small prismated hexatera, 21 small prismatodecachoric prisms, 21 small rhombated pentachoric prisms, 35 triangular-tetrahedral duoprisms, and 35 triangular-cuboctahedral duoprisms. 1 small rhombated hexateron, 1 small prismated hexateron, 2 small prismatodecachoric prisms, 3 small rhombated pentachoric prisms, 1 triangular-tetrahedral duoprism, and 3 triangular-cuboctahedral duoprisms join at each vertex. As the name suggests, it is the penticantellation of the heptapeton.
