Teriprismated heptapeton

The teriprismated heptapeton or topal, also called the penticantellated heptapeton or penticantellated 6-simplex, is a convex uniform polypeton. 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.
