Great ditrigonary hecatonicosiprismatohecatonicosihexacosichoron

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