1331/1323, the aphrowe comma, is an 11-limit, and 3.7.11 subgroup, comma that is the difference between a stack of two intervals of 11/7 and 27/11. Tempering it out in the 3.7.11 subgroup provides Mintaka temperament, which is one of the simplest temperaments in this subgroup with decent accuracy, and creates a 5L 2s macrodiatonic scale generated by 11/7 against the tritave.
