Great ditrigonary prismatodishecatonicosidishexacosichoron

The great ditrigonary prismatodishecatonicosidishexacosichoron, or gidditpid hiddix, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 icosidodecahedra, 120 great icosicosidodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Three octahedra, three icosidodecahedra, six great icosicosidodecahedra, twelve decagrammic prisms, and six cubohemioctahedra join at each vertex.
