In fact in the [[7-limit]] it tempers out [[1728/1715]], [[3136/3125]], and [[5120/5103]], and in the 11-limit, 176/175, [[540/539]], 1331/1323, [[1375/1372]], and notably the [[quartisma]].

It is a particularly good tuning for the 11- or 13-limit versions of [[semisept]], the {{nowrap|31 & 80}} temperament, and [[buzzard]], the {{nowrap|53 & 58}} temperament. [[Gene Ward Smith]]'s trio in [[#Music]] section is in [[Orwellismic family #Guanyin|guanyin temperament]], the [[planar temperament]] [[tempering out]] 176/175 and 540/539, for which 111 also provides the optimal patent val.

Since 111 factors into 3 × 37, 111edo contains [[3edo]] and [[37edo]] as its subsets. Of these, 37edo has the same approximations of several prime harmonics, notably 5, 7, 11, and 13, and thus offers the same accuracy in the no-3s [[13-odd-limit]]. [[333edo]], which slices the step of 111edo in three, is a significant tuning.
