Small skewverted prismatohecatonicosihexacosihecatonicosachoron

The small skewverted prismatohecatonicosihexacosihecatonicosachoron, or sik vaphixhi, is a nonconvex uniform polychoron that consists of 720 decagrammic prisms, 120 icosidodecatruncated icosidodecahedra, 120 great rhombicosidodecahedra, and 600 truncated octahedra. Two decagrammic prisms, two icosidodecatruncated icosidodecahedra, 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.
