Small skewverted hexacosihecatonicosidishecatonicosachoron

The small skewverted hexacosihecatonicosidishecatonicosachoron, or sik vixhidy, is a nonconvex uniform polychoron that consists of 120 great dodecicosahedra, 120 small rhombidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 600 truncated octahedra. One great dodecicosahedron, one small rhombidodecahedron, two icosidodecatruncated icosidodecahedra, 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.
