Small ditrigonary dishecatonicosihecatonicosachoron

The small ditrigonary dishecatonicosihecatonicosachoron, or sidtid hihy, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 rhombidodecadodecahedra, and 120 great ditrigonal dodecicosidodecahedra. Two small ditrigonary icosidodecahedra, six rhombidodecadodecahedra, and six great ditrigonal dodecicosidodecahedra join at each vertex.

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