1L 12s is the MOS pattern Lssssssssssss with small steps ranging from 0\1 (0¢) to 1\13 (one step of 13edo ≈ 92.3¢).

This MOS, also called the Happy tridecatonic scale, has its first harmonic entropy minimum at 1/14edo-3/40edo, where 3:2 is +8 generators (Octacot). However, the absolute harmonic entropy minimum is Nautilus (3:2=-6 generators), and that is not complete until 14 tones.
