The grand rhombic great hecatonicosihexacosichoron, or garghix, is a nonconvex uniform polychoron that consists of 120 rhombicosahedra and 600 truncated octahedra. Two rhombicosahedra and four truncated octahedra join at each vertex.

Vertex coordinates

The vertices are the same as those of the regiment colonel, the small rhombated grand stellated hecatonicosachoron.
