[[24edo]], which doubles it, improves significantly on approximations to 11 and 13, with 13 tuned sharp. [[36edo]], which triples it, improves on harmonics 7 and 13, but has the 13 tuned flat instead of sharp. [[72edo]] is a notable zeta-record edo, and [[60edo|60-]], [[84edo|84-]], and [[96edo]] all see utilities. Various [[12th-octave temperaments]] that augment 12edo exist, most prominent examples being [[compton]] and [[catler]]. | [[24edo]], which doubles it, improves significantly on approximations to 11 and 13, with 13 tuned sharp.
