Small retroinverted ditetrahedronary dishecatonicosachoron

The small retroinverted ditetrahedronary dishecatonicosachoron, or sridatady, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra and 120 small dodecicosidodecahedra. Four great ditrigonary icosidodecahedra and twelve small dodecicosidodecahedra join at each vertex.
