This uniform polyhedron compound is a composition of 5 stellated truncated hexahedra, formed by star-truncating each of the cubes in the compound of 5 cubes.

Cartesian coordinates

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

(±(2−2), ±2, ±(2−2))
(±φ, ±(φ−1−φ−12), ±(2φ−1−φ2))
(±1, ±(φ−2−12), ±(φ2−φ2))
(±(1−2), ±(−φ−2+2), ±(φ22))
(±(φ−φ2), ±(−φ−1), ±(2φ−1−φ−12))

where φ = (1+5)/2 is the golden ratio.
