This uniform polyhedron compound is a composition of 10 truncated tetrahedra, formed by truncating each of the tetrahedra in the compound of 10 tetrahedra. It also results from composing the two enantiomers of the compound of 5 truncated tetrahedra. It could also be called a truncated icosicosahedron.
Cartesian coordinates
Cartesian coordinates for the vertices of this compound are all the even permutations of
- (±1, ±1, ±3)
- (±τ−1, ±(−τ−2), ±2τ)
- (±τ, ±(−2τ−1), ±τ2)
- (±τ2, ±(−τ−2), ±2)
- (±(2τ−1), ±1, ±(2τ − 1))
where τ = (1+√5)/2 is the golden ratio (sometimes written φ).
