The grand ditetrahedronary prismatodishecatonicosihexacosichoron, or gadtapdahix, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 great icosidodecahedra, 720 pentagrammic prisms, and 120 great rhombidodecahedra. Four tetrahedra, six great icosidodecahedra, twelve pentagrammic prisms, and twelve great rhombidodecahedra join at each vertex.

Vertex coordinates

Its vertices are the same as those of its regiment colonel, the grand ditetrahedronary hexacosidishecatonicosachoron.
