13L 1s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 13 large steps and 1 small step, repeating every octave. 13L 1s is related to 1L 9s, expanding it by 4 tones. Generators that produce this scale range from 85.7¢ to 92.3¢, or from 1107.7¢ to 1114.3¢. Scales of this form are always proper because there is only one small step. This scale is notable for corresponding to octacot[14].
