Great cellated heptapeton

The great cellated heptapeton or gacal, also called the steriruncicantitruncated heptapeton or steriruncicantitruncated 6-simplex, is a convex uniform polypeton. 2 great cellidodecatera, 1 great prismated hexateron, 1 great rhombated pentachoric prism, 1 hexagonal-truncated tetrahedral duoprism, and 1 triangular-truncated octahedral duoprism join at each vertex. As the name suggests, it is the steriruncicantitruncation of the heptapeton.
