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.

## Vertex coordinates[edit | edit source]

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