Great snubspinosnub prismatosnub dishexacositrishexacosichoron

The great snubspinosnub prismatosnub dishexacositrishexacosichoron, or gosanspos dextix, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra, 2400 cuboctahedra and 2400 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 great ditrigonal dodecicosidodecahedra, 600 great rhombidodecahedra, 600 truncated great icosahedra, and 3600 pentagonal prisms.

One small stellated dodecahedron, one icosahedron, four cuboctahedra and four cubohemioctahedra (eight compounds), one octahemioctahedron (one compound), five great ditrigonal dodecicosidodecahedra, five great rhombidodecahedra, five truncated great icosahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosiprismatodishecatonicosachora and 5 great spinocapped dipentary hexacositrishecatonicosachora. In the process, some of the cuboctahedron and cubohemioctahedron cells blend out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great diretrosnub disnub decahecatonicosadishexacosichoron.
