Small skewverted hexacositrishecatonicosachoron

The small skewverted hexacositrishecatonicosachoron, or sik vixathi, is a nonconvex uniform polychoron that consists of 600 cuboctahedra, 120 small dodecicosidodecahedra, 120 great icosicosidodecahedra, and 120 great rhombicosidodecahedra. 1 cuboctahedron, 1 small dodecicosidodecahedron, 1 great icosicosidodecahedron, and 2 great rhombicosidodecahedra join at each vertex.

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