3889edo is [[consistent]] to the [[27-odd-limit]], [[tempering out]] [[ | 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]]. | |||
