Small pseudorhombic disicositetrachoron

The small pseudorhombic disicositetrachoron, or spirdy, is a nonconvex uniform polychoron that consists of 24 truncated cubes, 96 triangular prisms, and 24 great rhombicuboctahedra. Two truncated cubes, two triangular prisms, and four great rhombicuboctahedra join at each vertex.

It can be constructed as the blend of 3 siphado, with the oho cells blending out.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated icositetrachoron.
