Great dispinosnub pentishexacosichoron

The great dispinosnub pentishexacosichoron, or gidnaspox, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra, 4800 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 quasirhombicosidodecahedra, 600 great dodecicosahedra, and 600 rhombicosahedra.

One small stellated dodecahedron, one icosahedron, eight cubohemioctahedra (eight compounds), five quasirhombicosidodecahedra, five great dodecicosahedra, and five rhombicosahedra join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosihecatonicosachora and 5 great dipentary hexacosihecatonicositrishecatonicosachora. 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.
