Great dispinosnub prismatodisnub dishexacositetrishexacosichoron

The great dispinosnub prismatodisnub dishexacositetrishexacosichoron, or gidnaspid sodixtux, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 truncated great icosahedra, 600 great rhombidodecahedra, 600 icosidodecadodecahedra, 600 great ditrigonal dodecicosidodecahedra, and 6000 triangular prisms.

Two small stellated dodecahedra (two compounds), eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five great rhombidodecahedra, five icosidodecadodecahedra, five great ditrigonal dodecicosidodecahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great spinocapped dipentary hexacositrishecatonicosachora and 5 great capped dipentary prismatodishecatonicosihexacosihecatonicosachora. 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.
