The small intercepted ditetrahedronary trishecatonicosachoron, or sand tathi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 dodecahedra, and 120 small dodecicosidodecahedra. Four small ditrigonary icosidodecahedra, four dodecahedra, 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.
