385et tempers out following commas:
385edo has a reasonable approximation to the [[11-limit]], and perhaps beyond. The equal temperament [[tempering out|tempers out]] [[19683/19600]], [[589824/588245]], and [[703125/702464]] in the [[7-limit]]; [[540/539]], [[8019/8000]], [[43923/43904]], [[151263/151250]], [[160083/160000]], 166698/166375, and 172032/171875 in the 11-limit. It [[support]]s [[hemipental]] and provides the [[optimal patent val]] for the 7-limit version thereof.


7-limit commas: 589824/588245, 134217728/133984375, [[703125/702464]], 1959552/1953125, 5250987/5242880, 200120949/200000000
Using the [[patent val]], it tempers out [[1575/1573]], [[1716/1715]], [[2200/2197]], [[4096/4095]], [[6656/6655]], and [[10648/10647]] in the [[13-limit]]; and [[936/935]], [[1275/1274]], 1377/1375, and [[2601/2600]] in the [[17-limit]].
 
11-limit commas: 1073741824/1071794405, 161280/161051, 25165824/25109315, 234375/234256, 2097152/2096325, 1366875/1362944, 166698/166375, 496125/495616, 151263/151250, 104857600/104825259, [[540/539]], 172032/171875, 369140625/369098752, 825000/823543, 180224/180075, [[8019/8000]], 160083/160000, 539055/537824, 766656/765625, 202397184/201768035, 43923/43904, 20614528/20588575, 39135393/39062500, 781258401/781250000

385 factors into 5 x 7 x 11, with subset edos {{EDOs| 5, 7, 11, 35, 55, and 77 }}.
Since 385 factors into {{nowrap| 5 × 7 × 11 }}, 385edo has subset edos {{EDOs| 5, 7, 11, 35, 55, and 77 }}.
