Small ditrigonary hecatonicosiprismatohexacosihecatonicosachoron

The small ditrigonary hecatonicosiprismatohexacosihecatonicosachoron, or sidthippixhi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 small icosicosidodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Two small ditrigonary icosidodecahedra, six small icosicosidodecahedra, twelve decagrammic prisms, and six cubohemioctahedra join at each vertex.

Vertex coordinates
