191edo is inconsistent to the 5-odd-limit and higher limits, with two mappings possible for the 5-limit: ⟨191 303 443] (patent val) and ⟨191 303 444] (191c). Using the patent val, it tempers out the tetracot comma, 20000/19683 and [-52 5 19⟩ in the 5-limit; 245/243, 2401/2400, and 68359375/67108864 in the 7-limit; 385/384, 896/891, 1375/1372, and 118125/117128 in the 11-limit; 352/351, 364/363, 1625/1617, 1875/1859, and 2197/2187 in the 13-limit. Using the 191c val, it tempers out the amity comma, 1600000/1594323 and [39 -7 -12⟩ in the 5-limit; 4375/4374, 5120/5103, and 823543/810000 in the 7-limit; 441/440, 896/891, 6912/6875, and 14641/14580 in the 11-limit; 196/195, 352/351, 364/363, 2197/2187, and 3146/3125 in the 13-limit. Using the alternative 191cd val, it tempers out 1728/1715, 3136/3125, and 1605632/1594323 in the 7-limit; 176/175, 540/539, 1331/1323, and 655360/649539 in the 11-limit; 351/350, 352/351, 640/637, 1573/1568, and 2197/2187 in the 13-limit, supporting the semisept temperament.
