The '''391 equal division''' divides the octave into 391 equal parts of 3.069 cents each. It tempers out 5120/5103 and 420175/419904 in the 7-limit, and provides the [[Optimal_patent_val|optimal patent val]] for the hemifamity planar temperament and [[Hemifamity_temperaments#Septiquarter|septiquarter]], the 5&94 temperament. It tempers out 6250/6237, 4000/3993, 5632/5625 and 3025/3024 in the 11-limit and 676/675, 1716/1715 and 4225/4224 in the 13-limit, and provides further optimal patent vals for temperaments tempering out 5120/5103 such as [[Hemifamity_temperaments#Alphaquarter|alphaquarter]]. The 391bcde val provides a tuning for 11-limit miracle very close to the POTE tuning.

391edo has a sharp tendency, with [[prime harmonic]]s 3 to 13 all tuned sharp.

As an equal temperament, it [[tempering out|tempers out]] [[5120/5103]], [[420175/419904]], and [[29360128/29296875]] in the [[7-limit]], and provides the [[optimal patent val]] for the [[aberschismic]] temperament, and [[septiquarter]], the {{nowrap| 99 & 292 }} temperament. It tempers out [[3025/3024]], [[4000/3993]], [[5632/5625]], and [[6250/6237]] in the [[11-limit]]; and [[676/675]], [[1716/1715]] and [[4225/4224]] in the [[13-limit]], and provides further optimal patent vals for temperaments tempering out 5120/5103 such as [[alphaquarter]].

The 391bcde [[val]] provides a tuning for 11-limit miracle very close to the [[POTE tuning]].

=== Odd harmonics ===

=== Subsets and supersets ===

Since 391 factors into primes as {{nowrap| 17 × 23}}, 391edo contains [[17edo]] and [[23edo]] as subsets.
