382et is consistent to the [[7-odd-limit]] and the harmonic 3 is about halfway between its steps. Using the patent val, it tempers out [[65625/65536]] in the 7-limit; [[117440512/117406179]], 25165824/25109315, 2097152/2096325, [[4000/3993]], 2734375/2725888, 2359296/2358125, [[540/539]], 1265625/1261568, 24057/24010 and [[9801/9800]] in the 11-limit. It [[support]]s [[bastille]].
382edo is [[consistent]] to the [[7-odd-limit]], but [[harmonic]]s [[3/1|3]] and [[7/1|7]] are about halfway between its steps. It is also bad at approximating [[11/1|11]], [[13/1|13]], [[15/1|15]], and [[17/1|17]], though its [[5/1|5]], [[9/1|9]], [[19/1|19]], [[21/1|21]], and [[23/1|23]] are good, making it suitable for a 2.9.5.21.19.23 [[subgroup]] interpretation.
 
Using the [[patent val]] nonetheless, the equal temperament [[tempering out|tempers out]] [[65625/65536]] in the 7-limit; [[540/539]], [[4000/3993]], and [[9801/9800]] in the 11-limit. It [[support]]s [[bastille]].

382 factors into 2 × 191 with [[2edo]] and [[191edo]] as its subset edos. [[764edo]], which doubles it, gives a good correction to the harmonic 3.
