6L 13s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 6 large steps and 13 small steps, repeating every octave. 6L 13s is a grandchild scale of 6L 1s, expanding it by 12 tones. Generators that produce this scale range from 189.5 ¢ to 200 ¢, or from 1000 ¢ to 1010.5 ¢.

This MOS divides its small steps 2-2-2-2-2-3, like the hexatonic scale from 13edo. Its generator is a "neutral" whole tone between 3/19edo (189.474 cents) and 1/6edo (200 cents), making it index 2 in meantone. ("Neutral" as in neutrality between 10/9 and 9/8.)
