Cartesian coordinates
[edit]Cartesian coordinates for the vertices of this compound are all the cyclic permutations of
- (±(2−√2), ±√2, ±(2−√2))
- (±φ, ±(φ−1−φ−1√2), ±(2φ−1−φ√2))
- (±1, ±(φ−2+φ−1√2), ±(φ2−φ√2))
- (±(1−√2), ±(−φ−2+√2), ±(φ2−√2))
- (±(φ−φ√2), ±(−φ−1), ±(2φ−1−φ−1√2))
where φ = (1+√5)/2 is the golden ratio.
