Theory

1323edo is the smallest edo distinctly consistent in the 29-odd-limit. It is enfactored in the 7-limit, sharing the same excellent 7-limit approximation with 441edo, but it makes for a great higher-limit system by splitting each step of 441edo into three.

It provides the optimal patent val for the 11-limit trinealimmal temperament, which has a period of 1\27 octave.
