=== 26edo (demonstrated to work but awaiting approval) ===

With the fifth ~[[3/2]] being divisible by 5 (going from 15\26 down to 3\26, which is a near-just lesser tridecimal neutral second ~[[13/12]]), [[26edo]] supports [[fifive]] temperament, as shown in [[Bryan Deister]]'s [https://www.youtube.com/shorts/WvnJb5VNGj4 ''<nowiki>Caprice in 26edo [short clip]</nowiki>''] (2026). This uses 3\26 as the (rightward) generator, and splits the octave in half. Two of these make a sharp septimal minor third ~[[7/6]] which also functions as a flat tridecimal minor third ~[[13/11]], or a mildly flat diatismic minor third ~[[20/17]]; three of these make a very flat septimal major third ~[[9/7]] or a slightly flat undecimal (pentacircle) major third ~[[14/11]]; four of these make a slightly sharp undecimal major fourth ~[[11/8]]; five of these make a very flat fifth ~3/2 if bypassing the semioctave-reduction or a very flat al-Farabi quarter tone ~[[33/32]] with the semioctave-reduction. The range is about 4¾ octaves, and the octaves slope upwards so gently that it is tempting to move the note 0 position and using the generous allotment of repeated notes to split this mapping into two manuals.
