The grand ditrigonary dishecatonicosihexacosihecatonicosachoron, or gaddit dahixhi, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 icosidodecahedra, 120 rhombidodecadodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Three octahedra, three icosidodecahedra, six rhombidodecadodecahedra, and six small ditrigonal dodecicosidodecahedra join at each vertex.

Vertex coordinates

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