Terigreatoprismated heptapeton

The terigreatoprismated heptapeton or tagopal, also called the pentiruncicantitruncated heptapeton or pentiruncicantitruncated 6-simplex, is a convex uniform polypeton. It consists of 7 great prismated hexatera, 7 celligreatorhombated hexatera, 21 prismatorhombated pentachoric prisms, 21 great prismatodecachoric prisms, 35 hexagonal-cuboctahedral duoprisms, and 35 triangular-truncated octahedral duoprisms. 1 great prismated hexateron, 1 celligreatorhombated hexateron, 1 prismatorhombated pentachoric prism, 2 great prismatodecachoric prisms, 1 hexagonal-cuboctahedral duoprism, and 1 triangular-truncated octahedral duoprism join at each vertex. As the name suggests, it is the pentiruncicantitruncation of the heptapeton.
