The great rhombic trishecatonicosachoron, or grithi, is a nonconvex uniform polychoron that consists of 120 great rhombidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 120 great rhombicosidodecahedra. One great rhombidodecahedron, two icosidodecatruncated icosidodecahedra, and two great rhombicosidodecahedra join at each vertex.

Vertex coordinates[edit | edit source]

Its vertices are the same as those of its regiment colonel, the hecatonicosihexacositruncated hexacosihecatonicosachoron.
