Quasitruncated hexahedron

The quasitruncated hexahedron, the quasitruncated cube, or quith, is a uniform polyhedron. It consists of 8 triangles and 6 octagrams. Each vertex joins one triangle and two octagrams. As the name suggests, it can be obtained by quasitruncation of the cube.

Vertex coordinates
A quasitruncated hexahedron of edge length 1 has vertex coordinates given by all permutations and sign changes of
 * (±($\sqrt{7-4√2}$–1)/2, ±($\sqrt{2}$–1)/2, ±1/2).
