157edt is related to [[99edo]], but with the 3/1 rather than the [[2/1]] being just. The octave is about 0.~~6781~~ cents ~~compressed~~. 157edt is [[consistent]] to the [[integer limit|12-integer-limit]]. In comparison, 99edo is only consistent up to the 10-integer-limit. 157edt is notable for its excellent 5/3, as a convergent to log<sub>3</sub>(5), and can be used effectively both with and without twos.
