Small disnub prismatosnub dishexacositrishexacosichoron

The small disnub prismatosnub dishexacositrishexacosichoron, or sidsaps dextix, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (some of which lie in the same hyperplanes, forming 600 small retrosnub disoctahedra), 600 icosahedra, 4800 cuboctahedra (forming 2400 compounds of two), 600 small rhombidodecahedra, 600 small ditrigonal dodecicosidodecahedra, and 3600 pentagrammic prisms.

Two great icosahedra (two compounds), one icosahedron, eight cuboctahedra (six compounds), five small rhombidodecahedra, five small ditrigonal dodecicosidodecahedra, and five pentagrammic prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary hecatonicosihexacosidishecatonicosachora and 5 small dipentary hexacosiprismatodishecatonicosachora.

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