Rectified great ditrigonary hexacosihecatonicosachoron

The rectified great ditrigonary hexacosihecatonicosachoron, or riggidtixhi, is a nonconvex uniform polychoron that consists of 600 regular octahedra, 120 great ditrigonary icosidodecahedra, and 120 icosidodecahedra. 2 great ditrigonary icosidodecahedra, 3 icosidodecahedra, and 3 octahedra join at each tripod prismatic vertex. As the name suggests, it can be obtained by rectifying the great ditrigonary hexacosihecatonicosachoron.

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