Quasitruncated hexahedral prism

The quasitruncated hexahedral prism or quithip, is a prismatic uniform polychoron that consists of 2 quasitruncated hexahedra, 6 octagrammic prisms, and 8 triangular prisms. Each vertex joins 1 quasitruncated hexahedron, 1 octagrammic prism, and 2 triangular prisms. As the name suggests, it is a prism based on the quasitruncated hexahedron.

The quasitruncated hexahedral prism can be vertex-inscribed into the sphenoverted tesseractitesseractihexadecachoron and the great distetracontoctachoron.

Vertex coordinates
The vertices of a quasitruncated hexahedral prism of edge length 1 are given by all permutations of the first three coordinates of:
 * (±($\sqrt{2–√2}$–1)/2, ±($\sqrt{2–√2}$–1)/2, ±1/2, ±1/2).
