986edo is a good 2.3.7.11 subgroup tuning, but it is in[[consistent]] to the 5-odd-limit and larger due to a high error on the [[5/4|5th harmonic]]. 986edo has an excellent [[11/8|11th harmonic]], being the denominator of a [[convergent]] to log<sub>2</sub>11, after [[949edo|949]] and before [[1935edo|1935]]. In the 2.3.7.11 subgroup, 986edo can be used with optional additions of either [[17/16|17]], [[23/16|23]], [[29/16|29]], or [[31/16|31]]. | 986edo is a good 2.3.7.11 subgroup tuning, but it is in[[consistent]] to the 5-odd-limit and larger due to a high error on the [[5/4|5th harmonic]]. 986edo has an excellent [[11/8|11th harmonic]], being the denominator of a [[convergent]] to log<sub>2</sub>11, after [[949edo|949]] and before [[1935edo|1935]].

In the 2.3.7 subgroup, 986edo tempers out the [[garischisma]], and is a strong tuning for 2.3.7.11-subgroup [[gary]]. It also tempers out, 131072/130977, 3195731/3188646, 33554432/33480783, 67110351/67108864, and {{monzo|5 4 0 28 -26}} in the 2.3.7.11 subgroup. | In the 2.3.7 subgroup, 986edo tempers out the [[garischisma]], and is a strong tuning for 2.3.7.11-subgroup [[gary]].
