182 equal divisions of the octave (abbreviated 182edo or 182ed2), also called 182-tone equal temperament (182tet) or 182 equal temperament (182et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 182 equal parts of about 6.59 ¢ each. Each step represents a frequency ratio of 2^1/182, or the 182nd root of 2.

182edo is inconsistent to the 5-odd-limit and higher limits, with three mappings suitable for the 11-limit: ⟨182 288 423 511 630] (patent val), ⟨182 289 423 511 630] (182b), and ⟨182 288 422 511 629] (182ce). It does have a potential as a 2.9.15.7.17.19 subgroup temperament.

Using the patent val, it tempers out the mynic comma, 10077696/9765625 and [-27 20 -2⟩ in the 5-limit; 126/125, 1728/1715, and [-28 18 1 -1⟩ in the 7-limit; 2187/2156, 2835/2816, 5632/5625, and 14700/14641 in the 11-limit; 364/363, 676/675, 1287/1280, and 1701/1690 in the 13-limit. Using the 182f val, 144/143, 847/845, 1001/1000, and 1716/1715 are tempered out in the 13-limit.

Using the 182ce val, it tempers out the kleisma, 15625/15552 and the python comma, 43046721/41943040 in the 5-limit; 2430/2401, 33075/32768, and 78125/76832 in the 7-limit; 243/242, 385/384, 2420/2401, and 6250/6237 in the 11-limit; 351/350, 1188/1183, 1287/1280, 1575/1573, and 1625/1617 in the 13-limit.

Using the 182b val, it tempers out the diaschisma, 2048/2025 and [-4 -37 27⟩; in the 5-limit; 245/243, 6144/6125, and 9882516/9765625 in the 7-limit; 3025/3024, 3773/3750, and 4000/3993 in the 11-limit. Using the 182bf val, 196/195, 325/324, 364/363, and 1001/1000 are tempered out in the 13-limit. The 182bef val supports the shrutar temperament in the 19-limit and petrtri in the 2.11/5.13/5 subgroup.
