Template:EDO intro

771edo is distinctly consistent up to the 21-odd-limit, with all of the primes to 19 having a flat tendency.

In the 5-limit it tempers out the monzisma, [54 -37 2, and the mutt comma, [-44 -3 21; in the 7-limit 65625/65536 and 250047/250000; in the 11-limit 3025/3024; in the 13-limit 4225/4224 and 10648/10647; in the 17-limit 833/832, 1225/1224, 2058/2057, 2431/2430 and 2601/2600; and in the 19-limit 1445/1444, 1540/1539, 1729/1728, 2926/2925, 3250/3249, 4200/4199 and 5985/5984. It provides the optimal patent val for the rank-6 temperament tempering out 833/832 and various other temperaments tempering it out.
