'''[[Edt|Division of the third harmonic]] into 157 equal parts''' (157EDT) is related to [[99edo|99 edo]], but with the 3/1 rather than the 2/1 being just. The octave is about 0.6781 cents compressed and the step size is about 12.1144 cents. It is consistent to the [[11-odd-limit|12-integer-limit]]. In comparison, 99edo is only consistent up to the [[9-odd-limit|10-integer-limit]].

157edt is related to [[99edo]], but with the 3/1 rather than the [[2/1]] being just. The octave is [[stretched and compressed tuning|compressed]] by about 0.678 cents. 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.

=== Subsets and supersets ===

157edt is the 37th [[prime equal division|prime edt]]. It does not contain any nontrivial edts as subsets.
