165edo is inconsistent to the 5-odd-limit and higher limits, 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 [-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) 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.
