Great dispinosnub snub prismatosnubdisnub pentishexacosipentishecatonicosachoron

The great dispinosnub snub prismatosnubdisnub pentishexacosipentishecatonicosachoron, or gadinsospis dispoxphi, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra and 600 great icosahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 600 great dodecahedra and 600 icosahedra (forming 600 compounds of one of each), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 truncated great icosahedra, 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra), 3600 pentagonal prisms, and 6000 triangular prisms.

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

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