Great dispinosnub prismatosnub dishexacosipentishexacosichoron

The great dispinosnub prismatosnub dishexacosipentishexacosichoron, or gednasposid xopex, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 600 great dodecahedra and 600 icosahedra (forming 600 compounds of one of each), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 truncated great icosahedra, 600 great dodecicosahedra, 600 quasirhombicosidodecahedra, and 3600 pentagonal prisms.

Two small stellated dodecahedra (two compounds), one great dodecahedron and one icosahedron (two compounds), eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five great dodecicosahedra, five quasirhombicosidodecahedra, and five pentagonal prisms join at each vertex.

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