This uniform polyhedron compound is a symmetric arrangement of 10 hexagonal prisms, aligned with the axes of three-fold rotational symmetry of an icosahedron. Cartesian coordinates Cartesian coordinates for the vertices of this compound are all the cyclic permutations of (±, ±(τ−1−τ), ±(τ+τ−1)) (±2, ±τ−1, ±τ) (±(1+), ±(1−τ), ±(1+τ−1)) (±(τ−τ−1), ±, ±(τ−1+τ)) (±(1−τ−1), ±(1−), ±(1+τ)) where τ = (1+)/2 is the golden ratio (sometimes written φ).
