Celligreatorhombated heptapeton

The celligreatorhombated heptapeton or cagral, also called the stericantitruncated heptapeton or stericantitruncated 6-simplex, is a convex uniform polypeton. It consists of 7 celligreatorhombated hexatera, 7 prismatotruncated hexatera, 21 small rhombated pentachoric prisms, 35 hexagonal-octahedral duoprisms, and 35 triangular-truncated octahedral duoprisms. 2 celligreatorhombated hexatera, 1 prismatotruncated hexateron, 1 small rhombated pentachoric prism, 1 hexagonal-octahedral duoprism, and 2 triangular-truncated octahedral duoprisms join at each vertex. As the name suggests, it is the stericantitruncation of the heptapeton.
