Great dispinosnub trishexacositetrishexacosichoron

The great dispinosnub trishexacositetrishexacosichoron, or gidnastixtux, 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), 600 rhombidodecadodecahedra, 600 great dodecicosahedra, 600 quasirhombicosidodecahedra, and 600 truncated great icosahedra.

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

It can be obtained as the blend of 5 great capped dipentary tetrishecatonicosihexacosichora 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.
