17L 1s

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.
