Great dispinosnub prismatosnubdisnub dishexacositrishexacosichoron

The great dispinosnub prismatosnubdisnub dishexacositrishexacosichoron, or gednasposid sedaxtix, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 great dodecahedra, 4800 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 great dodecicosahedra and 600 great ditrigonal dodecicosidodecahedra (forming 600 compounds of one of each), 600 icosidodecadodecahedra, 3600 pentagonal prisms, and 6000 triangular prisms.

One small stellated dodecahedron, one great dodecahedron, eight cubohemioctahedra (eight compounds), five great dodecicosahedra and five great ditrigonal dodecicosidodecahedra (ten compounds), five icosidodecadodecahedra, five pentagonal prisms, and five triangular prisms join at each vertex.

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