The great ditrigonary trishecatonicosiprismatodishexacosichoron, or giddit thipdix, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 600 octahedra, 120 icosidodecahedra, 120 icosidodecadodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Two small ditrigonary icosidodecahedra, three octahedra, three icosidodecahedra, six icosidodecadodecahedra, twelve decagrammic prisms, and six cubohemioctahedra join at each vertex.

Vertex coordinates

Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
