'''165edo''' is the [[EDO|equal division of the octave]] into 165 parts of 7.2727 [[cent]]s each. It is inconsistent to the 5-limit and higher limit, with two mappings possible for the 5-limit: <165 262 383| (patent val) and <165 261 383| (165b). Using the patent val (with a sharp fifth), it tempers out 1638400/1594323 (immunity comma) and 1220703125/1207959552 (ditonma) in the 5-limit; 4000/3969, 65625/65536, and 84035/82944 in the 7-limit; 385/384, 2401/2376, 3388/3375, and 6655/6561 in the 11-limit; 196/195, 364/363, 676/675, 3185/3168, and 3200/3159 in the 13-limit.

165edo is in[[consistent]] to the [[5-odd-limit]] and higher limits, with two mappings possible for the 5-limit: {{val| 165 262 383 }} ([[patent val]]) and {{val| 165 '''261''' 383 }} (165b).

Using the patent val (with a sharp fifth), it tempers out 1638400/1594323 ([[immunity comma]]) and {{monzo| -27 -2 13 }} ([[ditonma]]) in the 5-limit; [[4000/3969]], [[65625/65536]], and 84035/82944 in the 7-limit; [[385/384]], 2401/2376, [[3388/3375]], and 6655/6561 in the 11-limit; [[196/195]], [[364/363]], [[676/675]], 3185/3168, and 3200/3159 in the 13-limit.

Using the 165b val (with a flat fifth), it tempers out 34171875/33554432 ([[ampersand comma]]) and 129140163/125000000 in the 5-limit; [[225/224]], [[1029/1024]], and 100442349/97656250 in the 7-limit; 1944/1925, 2187/2156, [[4000/3993]], and [[12005/11979]] in the 11-limit; [[144/143]], [[351/350]], [[625/624]], [[847/845]], and 9261/9152 in the 13-limit. Using the 165bf val, it tempers out 364/363, 975/968, [[1001/1000]], 1701/1690, and [[1716/1715]] in the 13-limit.

Since 165 factors into 3 × 5 × 11, 165edo has subset edos {{EDOs| 3, 5, 11, 15, 33, and 55 }}. [[330edo]], which doubles it, provides good correction for the approximation of harmonic 3.
