Grand ditetrahedronary prismatocubihexacosichoron

The grand ditetrahedronary prismatocubihexacosichoron, or gadtapicax, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), and 1200 triangular prisms. Four tetrahedra, eight cubes (or four compounds), and twelve triangular prisms join at each vertex.
