10L 3s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 10 large steps and 3 small steps, repeating every octave. 10L 3s is a child scale of 3L 7s, expanding it by 3 tones. Generators that produce this scale range from 830.8¢ to 840¢, or from 360¢ to 369.2¢.
A tempered-flat chain of the 13th harmonic really comes into its own as a distinct scale when extended to 13 tones. In these "Luach" (Hebrew calendar) modes the degrees are to be taken as numbered in descending order so that the the tempered 13th harmonic is fifth rather than tenth in the scale. This inverts the meaning of major and minor so that the Ionian-like mode reaches its degrees almost exclusively by backtracking.
Luachoid is a proposed name for this scale.
