566edo is [[consistency|distinctly consistent]] in the [[15-odd-limit]]. | 566edo is [[consistency|distinctly consistent]] in the [[15-odd-limit]]. As an equal temperament, it [[tempering out|tempers out]] the [[schisma]] in the 5-limit; 4375/4374 ([[ragisma]]), 65625/65536 ([[horwell comma]]), and 14348907/14336000 ([[skeetsma]]) in the 7-limit; [[3025/3024]] in the 11-limit; [[1716/1715]] and [[2080/2079]] in the 13-limit.

The 566g val is interesting in the higher limits, and in the 23-limit in particular it has a great rating in terms of absolute error.
