Small ditrigonary hexacosidishecatonicosachoron

The small ditrigonary hexacosidishecatonicosachoron, or sidtixady, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 small icosicosidodecahedra, and 600 octahemioctahedra. Two small ditrigonary icosidodecahedra, six small icosicosidodecahedra, and six octahemioctahedra join at each vertex.

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