Small retroinverted ditetrahedronary trishecatonicosachoron

The small retroinverted ditetrahedronary trishecatonicosachoron, or sridtathi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 dodecahedra, and 120 icosidodecahedra. Four small ditrigonary icosidodecahedra, four dodecahedra, and six icosidodecahedra join at each vertex.

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