Great dispinosnub prismatodisnub trishexacositrishexacosichoron

The great dispinosnub prismatodisnub trishexacositrishexacosichoron, or gidnaspid stextix, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra and 600 great icosahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 600 great dodecahedra, 4800 cubohemioctahedra (forming 2400 compounds of two), 600 icosidodecadodecahedra, 600 great rhombidodecahedra, 600 great dodecicosahedra, and 6000 triangular prisms.

One small stellated dodecahedron and one great icosahedron (two compounds), one great dodecahedron, eight cubohemioctahedra (eight compounds), five icosidodecadodecahedra, five great rhombidodecahedra, five great dodecicosahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great capped dipentary hexacositetrishecatonicosachora and 5 great dipentary hecatonicosiprismatohexacosihecatonicosachora. 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.
