Small ditrigonary tetrishecatonicosiprismatohexacosichoron

The small ditrigonary tetrishecatonicosiprismatohexacosichoron, or sidtuthipix, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 120 icosidodecahedra, 120 small icosicosidodecahedra, 120 great ditrigonal dodecicosidodecahedra, 720 decagonal prisms, and 600 cubohemioctahedra. Three great icosidodecahedra, three icosidodecahedra, six small icosicosidodecahedra, six great ditrigonal dodecicosidodecahedra, twelve decagonal prisms, and six cubohemioctahedra join at each vertex.
