Great ditetragonal spinoduoprism

The great ditetragonal spinoduoprism, or gidtindip, is a nonconvex uniform polychoron that consists of 32 tetrahedra, 64 triangular prisms, 64 cubes, and 16 great rhombihexahedra. One tetrahedron, three triangular prisms, four cubes, and three great rhombihexahedra join at each vertex.

It was discovered on March 2, 2006 by Jonathan Bowers following Mason Green's discovery of ondip and gondip.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great octagonal spinoduoprism.
