The **retroditetrahedronary trishecatonicosachoron**, or **radatathi**, is a nonconvex uniform polychoron that consists of 120 regular dodecahedra, 120 great stellated dodecahedra, and 120 dodecadodecahedra. 4 great stellated dodecahedra, 4 dodecahedra, and 6 dodecadodecahedra join at each vertex.

## Vertex coordinates[edit | edit source]

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