Grand ditetrahedronary prismatotrishecatonicosachoron

The grand ditetrahedronary prismatotrishecatonicosachoron, or gadtapthi, is a nonconvex uniform polychoron that consists of 120 great stellated dodecahedra, 120 great icosidodecahedra, 1200 triangular prisms, and 120 great rhombidodecahedra. Four great stellated dodecahedra, six great icosidodecahedra, twelve triangular prisms, and twelve great rhombidodecahedra join at each vertex.
