Great dispinosnub prismatosnub hexacosipentishexacosichoron

The great dispinosnub prismatosnub hexacosipentishexacosichoron, or gednasposaxpox, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 great dodecahedra and 600 icosahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 4800 cubohemioctahedra (forming 2400 compounds of two), 1200 truncated great icosahedra (forming 600 compounds of two), 600 quasirhombicosidodecahedra, and 3600 pentagonal prisms.

One small stellated dodecahedron, one great dodecahedron and one icosahedron (two compounds), eight cubohemioctahedra (eight compounds), ten truncated great icosahedra (ten compounds), five quasirhombicosidodecahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great capped dipentary prismatohexacositrishecatonicosachora and 5 great based dipentary hexacositrishecatonicosachora. In the process, some of the cubohemioctahedron cells blend out.

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