Great dispinosnub dishexacosi prismatosnub tetrishexacosichoron

The great dispinosnub dishexacosi prismatosnub tetrishexacosichoron, or gadinsadox postux, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 1200 great dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagonal retrosnub pseudodisoctahedra), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 great dodecicosahedra and 600 great icosicosidodecahedra (forming 600 compounds of one of each), 600 great rhombidodecahedra, and 3600 pentagonal prisms.

One great icosahedron, two great dodecahedra (two compounds), eight cubohemioctahedra (eight compounds), five great dodecicosahedra and five great icosicosidodecahedra (ten compounds), five great rhombidodecahedra, and five pentagonal prisms join at each vertex.

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