718edo is [[consistency|distinctly consistent]] in the [[23-odd-limit]], and does well enough in the 31-limit. It is closely related to [[359edo]], but the mapping differs for [[5/1|5]], [[13/1|13]], [[17/1|17]] and [[31/1|31]]. | 718edo is [[consistency|distinctly consistent]] in the [[23-odd-limit]], and does well enough in the 31-limit, with [[28/25]] and its octave complement [[25/14]] being the only inconsistencies in the [[35-odd-limit]].
