Small skewverted dishecatonicosidishexacosichoron

The small skewverted dishecatonicosidishexacosichoron, or sik vidhiddix, is a nonconvex uniform polychoron that consists of 600 cubohemioctahedra, 120 small rhombidodecahedra, 120 great rhombicosidodecahedra, and 600 truncated octahedra. One cubohemioctahedron, one small rhombidodecahedron, two great rhombicosidodecahedra, and two truncated octahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small skewverted ditrigonal prismatohexacosidishecatonicosachoron.
