The **small retroditetrahedronary dishecatonicosihexacosichoron**, or **sradditdahix**, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 600 tetrahedra, and 120 small dodecicosidodecahedra. Four ditrigonary dodecadodecahedra, four tetrahedra, and twelve small dodecicosidodecahedra join at each vertex.

## Vertex coordinates[edit | edit source]
