9L 15s
9L 6s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 9 large steps and 6 small steps, with a period of 3 large steps and 2 small steps that repeats every 400.0¢, or 3 times every octave. 9L 6s is a child scale of 6L 3s, expanding it by 6 tones. Generators that produce this scale range from 240¢ to 266.7¢, or from 133.3¢ to 160¢.
The period (400¢) minus one dark generator represents a 23+-limit interval between 23/20 and 7/6 (between ~242¢ to ~267¢).
