3L 4s
3L 1s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 3 large steps and 1 small step, repeating every octave. Generators that produce this scale range from 300¢ to 400¢, or from 800¢ to 900¢. Scales of this form are always proper because there is only one small step.
