Great dispinosnub tetrishexacosichoron

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

One small stellated dodecahedron, eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five great rhombidodecahedra, and five rhombicosahedra join at each vertex.

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