Great dispinosnub snub prismatosnub pentishecatonicositetrishexacosichoron

The great dispinosnub snub prismatosnub pentishecatonicositetrishexacosichoron, or gidansos posphitux, is a nonconvex uniform polychoron that consists of 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 great dodecicosahedra, 600 great rhombidodecahedra, 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra), and 3600 pentagonal prisms.

One great dodecahedron and one icosahedron (two compounds), eight cubohemioctahedra (eight compounds), five great dodecicosahedra, five great rhombidodecahedra, five truncated tetrahedra (one compound, four single), and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary hecatonicosiprismatohecatonicosihexacosichora and 5 great dipentary dishecatonicosidishexacosichora. 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.
