3889edo is [[consistent]] to the [[27-odd-limit]], [[tempering out]] [[12376/12375]], [[14400/14399]], [[6175/6174]], 8625/8624, 89376/89375, [[123201/123200]], 1549184/1549125 and [[1990656/1990625]] in the [[23-limit]]. It is strong in the 2.3.5.7.13.17.19.23.31 [[subgroup]], tempering out 6175/6174, 14365/14364, 426496/426465, 52326/52325, 52003/52000, 1549184/1549125, 1990656/1990625 and 22816/22815. The equal temperament also tempers out [[19251/19250]] in the 2.3.5.7.11.23.31 subgroup and [[5440/5439]] in the 2.3.5.7.17.37 subgroup.
3889edo is [[consistent]] to the [[27-odd-limit]], and except for [[29/19]] and its [[octave complement]], it is consistent to the [[31-odd-limit]].
 
As an equal temperament, it [[tempering out|tempers out]] the [[pirate comma]], the [[starscape comma]], and the [[quartisma]]. Some of the simpler commas it tempers out in the higher limits include [[6656/6655]], [[123201/123200]] and [[1990656/1990625]] in the [[13-limit]]; [[12376/12375]], [[14400/14399]] in the [[17-limit]]; [[5776/5775]], [[6175/6174]], 14365/14364, 23409/23408, 28900/28899, 43681/43680 in the [[19-limit]]; [[5083/5082]], 7866/7865, and 8625/8624 in the [[23-limit]].
