Truncated stella octangula

The truncated stella octangula, truncated stellated octahedron, tisso, or compound of two truncated tetrahedra is a uniform polyhedron compound. It consists of 8 triangles and 8 hexagons, with one triangle and two hexagons joining at each vertex. As the name suggests, it can be derived as the truncation of the stella octangula, the compound of two tetrahedra.

Its quotient prismatic equivalent is the truncated tetrahedral cupoliprism, which is four-dimensional.

Vertex coordinates
The vertices of a truncated stella octangula of edge length 1 can be given by all permutations of:


 * (±3$\sqrt{3}$/4, ±$\sqrt{3}$/4, ±$\sqrt{22}$/4)
