It is the optimal patent val for the 7-limit tritonic temperament and the 11-limit tritoni temperament, and the planar squalentine temperament. It tempers out 78732/78125 in the 5-limit; 225/224 in the 7-limit; 385/384 and 4000/3993 in the 11-limit; and 351/350 and 364/363 in the 13-limit.
122 is flat in tendency, with the odd primes from 3 to 13 tuned flat. 122 = 2 × 61. 122 = 55 + 67, and so using the 122c val it is the convergent towards 1/6-comma meantone, with a fifth just a hundredth of a cent flatter.
