Grand quasirhombic disicositetrachoron

The grand quasirhombic disicositetrachoron, or gaquerdy, is a nonconvex uniform polychoron that consists of 24 great rhombihexahedra and 24 quasitruncated cuboctahedra. Two great rhombihexahedra and four quasitruncated cuboctahedra join at each vertex.

It can be constructed as the blend of 3 great rhombiprismic tesseractihexadecachora. In the process the cubohemioctahedron cells blend 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.
