The small retroditetrahedronary distrishecatonicosachoron, or sirdatady, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra and 120 icosidodecahedra. Four great ditrigonary icosidodecahedra and six icosidodecahedra join at each vertex.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small ditetrahedronary hexacosihecatonicosachoron.
