Temperaments

Tempering out this comma in the 2.5.11 subgroup results in the jug temperament, generated by a meantone-like major second of 11/10~25/22, and in the no-twos-or-threes 5.7.11 subgroup it results in the nonoctave juggernaut temperament, with a period that is the square root of 5 (representing 11/5~25/11) and a generator of ~7/5.
