sLLLLLLLLLLLLLLLLL
17L 1s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 17 large steps and 1 small step, repeating every octave. 17L 1s is related to 1L 9s, expanding it by 8 tones. Generators that produce this scale range from 66.7¢ to 70.6¢, or from 1129.4¢ to 1133.3¢. Scales of this form are always proper because there is only one small step.
