10L 7s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 10 large steps and 7 small steps, repeating every octave. 10L 7s is a child scale of 7L 3s, expanding it by 7 tones. Generators that produce this scale range from 352.9¢ to 360¢, or from 840¢ to 847.1¢.

This scale is the neutral thirds version of Schismic temperament. The range of the bright generator also makes it an improper MOS of Beatles temperament (generator = c. 19\64 ~ 356.25 ¢).
