Great snubspinosnub prismatosnubdisnub trishexacosichoron

The great snubspinosnub prismatosnubdisnub trishexacosichoron, or gosenspasidstix, is a nonconvex uniform polychoron that consists of 600 icosahedra and 600 great dodecahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 2400 cuboctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 great dodecicosahedra, 3600 pentagonal prisms, and 6000 triangular prisms.

One icosahedron and one great dodecahedron (two compounds), four cuboctahedra and four cubohemioctahedra (eight compounds), one octahemioctahedron (one compound), five great dodecicosahedra, five pentagonal prisms, and five triangular prisms join at each vertex.

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