This scale is notable for corresponding to 15-note scales of temperaments like [[nautilus]] and [[sextilififths]].


6 steps of the scale cover a diatonic fourth, and they also go from the lower bound to upper bound of diatonic fourths (3\7 to 2\5) over the course of the entire step ratio spectrum, corresponding to going from 14edo perfect fourth to 15edo pefect fourth.
