The great ditrigonary dishecatonicosidishexacosihecatonicosachoron, or gidtid hidixhi, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 icosidodecahedra, 120 great icosicosidodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Three octahedra, three icosidodecahedra, six great icosicosidodecahedra, twelve quasitruncated dodecadodecahedra, and six cubohemioctahedra join at each vertex.
