Hexagrammic prism

The hexagrammic prism or compound of 2 triangular prisms is a prismatic uniform polyhedron compound. It consists of 2 hexagrams and 6 squares. Each vertex joins one hexagram and two squares. As the name suggests, it is a prism based on a hexagram.

Its quotient prismatic equivalent is the octahedral prism, which is four-dimensional.

Vertex coordinates
A hexagrammic prism of edge length 1 has vertex coordinates given by:
 * $$\left(0,\,±\frac{\sqrt3}{3},\,±\frac12\right),$$
 * $$\left(±\frac12,\,±\frac{\sqrt3}{6},\,±\frac12\right).$$
