Great rhombic disicositetrachoron

The great rhombic disicositetrachoron, or girdi, is a nonconvex uniform polychoron that consists of 24 quasitruncated hexahedra, 24 great rhombihexahedra, and 96 triangular prisms. 2 of each type of cell join at each vertex.

It can be constructed as the blend of 3 quasiprismatorhombated hexadecachora, with the cuboctahedron cells blending out and the octagrammic prisms blending into great rhombihexahedra.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the sphenoverted trisicositetrachoron.
