Great pseudorhombic disicositetrachoron

The great pseudorhombic disicositetrachoron, or gapirdy, is a nonconvex uniform polychoron that consists of 24 quasitruncated hexahedra, 96 triangular prisms, and 24 quasitruncated cuboctahedra. Two quasitruncated hexahedra, two triangular prisms, and four quasitruncated cuboctahedra join at each vertex.

It can be constructed as the blend of 3 great prismatohexadecadisoctachora. In the process the octahemioctahedron cells blend out.

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