Small ditrigonary trishecatonicosachoron

The small ditrigonary trishecatonicosachoron, or sidtithi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 small icosicosidodecahedra, and 120 rhombicosahedra. Two small ditrigonary icosidodecahedra, six small icosicosidodecahedra, and six rhombicosahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
