Great dispinosnub prismatosnubdisnub dishexacosidishexacosichoron

The great dispinosnub prismatosnubdisnub dishexacosidishexacosichoron, or gednasposid sadixdox, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (falling into pairs in the same hyperplanes, forming 600 small retrosnub disoctahedra), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 great dodecicosahedra and 600 great icosicosidodecahedra (forming 600 compounds of one of each), 6000 triangular prisms, and 3600 pentagonal prisms.

Two great icosahedra (two compounds), eight cubohemioctahedra (eight compounds), five great dodecicosahedra and five great icosicosidodecahedra (ten compounds), five triangular prisms, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary hecatonicosiprismatohexacosihecatonicosachora and 5 great dipentary prismatohecatonicosihexacosihecatonicosachora. 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.
