117edo is inconsistent to the 5-odd-limit and higher odd limits, with four mappings possible for the 11-limit: 117 185 272 328 405] (patent val), 117 186 272 329 405] (117bd), 117 185 271 328 404] (117ce), and 117 185 272 329 405] (117d).

Using the 117ce val, it tempers out 3125/3072 (magic comma) and [-31 24 -3 in the 5-limit; 2401/2400, 3645/3584, and 4375/4374 in the 7-limit; 243/242, 441/440, and 1815/1792 in the 11-limit; 105/104, 275/273, 1287/1280, and 2025/2002 in the 13-limit.

Using the 117bd val, it tempers out 15625/15552 (kleisma) and [34 -17 -3 in the 5-limit; 245/243, 3136/3125, and 51200/50421 in the 7-limit; 176/175, 1232/1215, 1375/1372, and 2560/2541 in the 11-limit; 169/168, 364/363, 640/637, 832/825, and 3200/3159 in the 13-limit.
