Inverted disicositetrachoron

The inverted disicositetrachoron, or idi, is a nonconvex uniform polychoron that consists of 24 quasitruncated hexahedra and 24 great cubicuboctahedra. Four quasitruncated hexahedra and four great cubicuboctahedra join at each vertex.

It can be constructed as the blend of 3 wavitoth, with the oct cells blending out.

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