11L 2s⟨3/1⟩ is a 3/1-equivalent (tritave-equivalent) moment of symmetry scale containing 11 large steps and 2 small steps, repeating every interval of 3/1 (1902.0¢). Generators that produce this scale range from 1024.1¢ to 1037.4¢, or from 864.5¢ to 877.8¢.

Having 11 large steps and 2 small steps, this MOS family is the first which is true Arcturus scale. However, it still has slightly smeary intonation regarding the generator (or major sixth), This smearing causes 3g to be so flat that it tritave reduces into the syntonic continuum of fifths, thus making these scales ridden with pseudo-octaves and pseudo-fifths.
