Great prismated heptapeton

The great prismated heptapeton or gapil, also called the runcicantitruncated heptapeton or runcicantitruncated 6-simplex, is a convex uniform polypeton. It consists of 7 great prismated hexatera, 7 great rhombated hexatera, 21 truncated pentachoric prisms, and 35 hexagonal-tetrahedral duoprisms. 3 great prismated hexatera, 1 great rhombated hexateron, 1 truncated pentachoric prism, and 1 hexagonal-tetrahedral duoprism join at each vertex. As the name suggests, it is the runcicantitruncation of the heptapeton.
