Great dispinosnub prismatosnub trishexacositetrishexacosichoron

The great dispinosnub prismatosnub trishexacositetrishexacosichoron, or gidan spostixtux, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 1200 great dodecahedra (forming 600 pentagonal retrosnub pseudodisoctahedra), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 truncated great icosahedra, 600 icosidodecadodecahedra, 600 great rhombidodecahedra, and 3600 pentagonal prisms.

Two small stellated dodecahedra (two compounds), two great dodecahedra (two compounds), eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five icosidodecadodecahedra, five great rhombidodecahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great capped dipentary prismatohexacositrishecatonicosachora and 5 great capped dipentary hexacositetrishecatonicosachora. 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.
