Great quasiprismatodishexadecachoron

The great quasiprismatodishexadecachoron, or gaquipadah, is a nonconvex uniform polychoron consisting of 16 regular tetrahedra, 24 triangular prisms, 16 cubes, and 8 octagrammic prisms. 1 tetrahedron, 3 triangular prisms, 2 cubes, and 2 octagrammic prisms meet each vertex. It can be created by blending a quasidisprismatotesseractihexadecachoron with an octagrammic diorthoprism, the inscribed compound of 2 square-octagrammic duoprisms. In the process 16 cubical cells blend out.

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