Small ditrigonary hecatonicosihexacosidishecatonicosachoron

The small ditrigonary hecatonicosihexacosidishecatonicosachoron, or sidthixady, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 600 octahedra, 120 icosidodecahedra, and 120 rhombidodecadodecahedra. Two small ditrigonary icosidodecahedra, three octahedra, three icosidodecahedra, and six rhombidodecadodecahedra join at each vertex.

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