Truncated tesseractihemioctachoron

The truncated tesseractihemioctachoron, or titho, is a nonconvex uniform polychoron that consists of 8 tetrahemihexahedra, 8 truncated tetrahedra, and 4 truncated octahedra. One tetrahemihexahedron, two truncated tetrahedra, and two truncated octahedra join at each vertex. As the name suggests, it can be obtained by truncating the tesseractihemioctachoron.

It is in the same regiment as the truncated hexadecachoron.
