8L 7s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 8 large steps and 7 small steps, repeating every octave. 8L 7s is a child scale of 7L 1s, expanding it by 7 tones. Generators that produce this scale range from 1040 ¢ to 1050 ¢, or from 150 ¢ to 160 ¢.

This MOS is the chromatic scale of Opossum temperament, which forms the tetrad 1-6\5-10\7-12\7 from steps 0-2-4-6 of its generator chain.
