86 = 2 × 43, and the [[patent val]] is a [[contorted]] [[43edo|43]] in the 5-limit. In the 7-limit the patent val tempers out 6144/6125, so that it [[support]]s mohajira temperament. In the 11-limit it tempers out [[245/242]], [[540/539]] and [[4000/3993]], and in the 13-limit [[144/143]], [[196/195]] and [[676/675]]. It provides the optimal patent val for the 13-limit 9 & 86 temperament tempering out 144/143, 196/195, 245/242 and 676/675.

86edo is closely related to the [[delta scale]], which is the equal division of the [[16/15|classic diatonic semitone]] into eight parts of 13.9664 cents each.

86edo contains [[2edo]] and [[43edo]] as subsets. [[258edo]], which triples it, is a notable tuning.
