Great prismatosnub disnub hexishexacosichoron

The great prismatosnub disnub hexishexacosichoron, or gopisdoshax, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 icosahedra, 4800 cuboctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 truncated great icosahedra, 600 rhombicosahedra, 600 great dodecicosidodecahedra, 600 great ditrigonal dodecicosidodecahedra, and 3600 pentagonal prisms.

One great icosahedron, one icosahedron, eight cuboctahedra (eight compounds), five truncated great icosahedra, five rhombicosahedra, five great dodecicosidodecahedra, five great ditrigonal dodecicosidodecahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosiprismatodishecatonicosachora and 5 great dipentary trishecatonicosihexacosihecatonicosachora. In the process, some of the cuboctahedron cells blend out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great diretrosnub disnub decahecatonicosadishexacosichoron.
