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
- (±√3, ±(τ−τ√3), ±(τ+τ√3))
- (±2√3, ±τ, ±τ)
- (±(1+√3), ±(1−τ√3), ±(1+τ√3))
- (±(τ−τ√3), ±√3, ±(τ+τ√3))
- (±(1−τ√3), ±(1−√3), ±(1+τ√3))
where τ = (1+√5)/2 is the golden ratio (sometimes written φ).
