Compound of five truncated tetrahedra

The compound of five truncated tetrahedra is a uniform polyhedron compound. It's composed of 5 truncated tetrahedra rotated around a common axis. It may be formed by truncating each of the tetrahedra in the compound of five tetrahedra. A far-enough truncation creates the compound of five octahedra. Its convex hull is a nonuniform snub dodecahedron. It could also be called a truncated chiricosahedron.

Cartesian coordinates

Cartesian coordinates for the vertices of this compound are all the cyclic permutations of

(±1, ±1, ±3)
(±τ<sup>−1</sup>, ±(−τ<sup>−2</sup>), ±2τ)
(±τ, ±(−2τ<sup>−1</sup>), ±τ<sup>2</sup>)
(±τ<sup>2</sup>, ±(−τ<sup>−2</sup>), ±2)
(±(2τ−1), ±1, ±(2τ − 1))

with an even number of minuses in the choices for '±', where τ = (1+)/2 is the golden ratio (sometimes written φ).
