Great dispinosnub prismatodisnub hexacosipentishexacosichoron

The great dispinosnub prismatodisnub hexacosipentishexacosichoron, or gadinspidos xopex, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (falling into pairs in the same hyperplanes, forming 600 small retrosnub disoctahedra), 600 great dodecahedra, 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 6000 triangular prisms.

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

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