Quasidisprismatotesseractihexadecachoron

The quasidisprismatotesseractihexadecachoron, or quidpith, is a nonconvex uniform polychoron that consists of 16 regular tetrahedra, 32 triangular prisms, and 8+24 cubes. 1 tetrahedron, 3 triangular prisms, and 1+3 cubes join at each vertex. It is the result of pushing the cells of either a tesseract or a hexadecachoron inwards.

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