Great dispinosnub heptishexacosichoron

The great dispinosnub heptishexacosichoron, or gednashox, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 600 great dodecahedra, 4800 cubohemioctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 great dodecicosahedra, 600 great rhombidodecahedra, and 600 truncated great icosahedra.

Two small stellated dodecahedra (two compounds), one great dodecahedron, eight cubohemioctahedra (eight compounds), five rhombidodecadodecahedra, five great dodecicosahedra, five great rhombidodecahedra, and five truncated great icosahedra join at each vertex.

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