The **small ditetrahedronary disprismatohecatonicosachoron**, or **sidtadphi**, is a nonconvex uniform polychoron that consists of 120 icosidodecahedra, 720 pentagonal prisms, and 1200 triangular prisms. Six icosidodecahedra, twelve pentagonal prisms, and twelve triangular prisms join at each vertex.

## Vertex coordinates[edit | edit source]
