Small prismatodisnub disnub dishexacositrishexacosichoron

The small prismatodisnub disnub dishexacositrishexacosichoron, or spods dusdextix, 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 rhombicosahedra, 600 small dodecicosahedra, and 6000 triangular prisms.

Two great icosahedra (two compounds), one icosahedron, eight cuboctahedra (eight compounds), five rhombicosahedra, five small dodecicosahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary prismatohexacosihecatonicosachora and 5 small based dipentary tetrishecatonicosihexacosichora.

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