The 39-odd-limit is the set of all rational intervals which can be written as 2k(a/b) where a, b ≤ 39 and k is an integer. To the 37-odd-limit, it adds 11 pairs of octave-reduced intervals involving 39.

Below is a list of all octave-reduced intervals in the 39-odd-limit.

Ratio Size (¢) Color name Name
40/39 43.831
39/38 44.97
39/37 91.139
39/35 187.343
44/39 208.835
39/34 237.527
46/39 285.792
39/31 397.447
50/39 430.145
39/29 512.905
39/28 573.657
56/39 626.343
58/39 687.095
39/25 769.855
62/39 802.553
39/23 914.208
68/39 962.473
39/22 991.165
70/39 1012.657
74/39 1108.861
76/39 1155.03
39/20 1156.169

The smallest equal division of the octave which is consistent to the 39-odd-limit is 311edo (by virtue of it being consistent in the 41-odd-limit); that which is distinctly consistent to the same is 20567edo (by virtue of it being distinctly consistent through the 57-odd-limit).
