The 364 equal divisions of the octave (364edo), or the 364(-tone) equal temperament (364tet, 364et) when viewed from a regular temperament perspective, is the equal division of the octave into 364 parts of about 3.30 cents each.
Theory
364edo is consistent through the 21-odd-limit, tempering out 1600000/1594323 (amity comma) and [-65 0 28⟩; (28-5-comma) in the 5-limit; 65625/65536 (horwell), 390625/388962 (dimcomp), and 420175/419904 (wizma) in the 7-limit (supporting fifthplus and oquatonic); 1375/1372, 6250/6237, 19712/19683, and 41503/41472 in the 11-limit (as well as 9801/9800); 625/624, 1716/1715, 2080/2079, 2200/2197, and 14641/14625 in the 13-limit (as well as 4096/4095, 4225/4224, and 10985/10976); 715/714, 1089/1088, 1225/1224, 1275/1274, 2025/2023, and 8624/8619 in the 17-limit (as well as 2431/2430, 4914/4913, and 5832/5831); 1216/1215, 1331/1330, 1540/1539, and 1729/1728 in the 19-limit.
364 is divisible by, and thus contains sub-edos 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182.
