186edo is closely related to 31edo, but the patent vals differ on the mapping for 3. The equal temperament tempers out 67108864/66430125 (misty comma) and 390625000/387420489 (quartonic comma) in the 5-limit, as well as 6115295232/6103515625 (vishnuzma); 3136/3125, 5120/5103 and 117649/116640 in the 7-limit. Using the patent val, it tempers out 385/384, 1331/1323, 2200/2187, and 3773/3750 in the 11-limit; 325/324, 352/351, 847/845, and 1573/1568 in the 13-limit.

Subsets and supersets
Since 186 factors into 2 × 3 × 31, 186edo has subset edos 2, 3, 6, 31, 62, and 93.
