2L 11s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 2 large steps and 11 small steps, repeating every octave. 2L 11s is a grandchild scale of 2L 7s, expanding it by 4 tones. Generators that produce this scale range from 553.8 ¢ to 600 ¢, or from 600 ¢ to 646.2 ¢.

This MOS is the minimal truly chromatic scale[clarification needed] of Liese, Triton, and Tritonic temperaments.
