81/80s equal temperament (AS81/80) is an equal multiplication of the syntonic comma. It corresponds to 55.79763 EDO.

Theory

81/80s equal temperament can be regarded as a subset of 5-limit just intonation.

Some intervals it approximates well are 5/4, 7/4, 12/11, 14/13, and 15/11. In addition, it represents well certain compound intervals such as 8/3, 11/1, 12/1 while omitting their octave reductions.

With a stretch, 53edo can be regarded as its ED2 equivalent.
