Theory
1277edo is consistent to the 11-odd-limit. The equal temperament tempers out 4375/4374, 52734375/52706752, 645700815/645657712 (starscape comma) and [51 -13 -1 -10⟩ (technologisma) in the 7-limit; 151263/151250, 759375/758912, and 2097152/2096325 in the 11-limit. It supports monzismic, supermajor, revopent, as well as the rank-3 temperament bragi.
