Small skewverted dishexacosidishecatonicosachoron

The small skewverted dishexacosidishecatonicosachoron, or sik vadixady, is a nonconvex uniform polychoron that consists of 600 octahemioctahedra, 600 truncated octahedra, 120 small rhombicosidodecahedra, and 120 great icosicosidodecahedra. 1 octahemioctahedron, 1 small rhombicosidodecahedron, 1 great icosicosidodecahedron, and 2 truncated octahedra join at each vertex.

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