4L 10s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 4 large steps and 10 small steps, with a period of 2 large steps and 5 small steps that repeats every 600.0¢, or twice every octave. 4L 10s is a child scale of 4L 6s, expanding it by 4 tones. Generators that produce this scale range from 257.1¢ to 300¢, or from 300¢ to 342.9¢.
The generator range puts a minor third (300 to 342.857 cents) -1 generator away from the period and 38edo almost exactly at the harmonic entropy minimum for its pattern.
