Great dispinosnub prismatosnubdisnub hexishexacosichoron

The great dispinosnub prismatosnubdisnub hexishexacosichoron, or gednasposidshox, 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 truncated great icosahedra, 600 icosidodecadodecahedra, 600 great ditrigonal dodecicosidodecahedra, 3600 pentagonal prisms, and 6000 triangular prisms.

Two small stellated dodecahedra (two compounds), one great dodecahedron, eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five icosidodecadodecahedra, five great ditrigonal dodecicosidodecahedra, five pentagonal prisms, and five triangular prisms join at each vertex.

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