* 19edo: The smallest edo after 12edo which supports [[Meantone]]. Just major and minor thirds are better approximated than in 12edo. First [[interordinal]] diatonic edo (interordinals are semifourths, semisixths, semitenths, and semitwelfths). | * 19edo: The smallest edo after 12edo which supports [[Meantone]].

* 22edo: Diatonic MOS with a fifth so sharp that it has supermajor and subminor thirds for its major and minor thirds. "Minor sevenths" such as A–G and C–B♭ are approximately 7/4 instead of 16/9 or 9/5. Has a 5-limit major third (approximate 5/4) which *cannot* be reached by stacking four fifths.
