~~108edo~~ tempers out the Pythagorean comma~~, 531441/524288,~~ in the 3-limit and 1990656/1953125~~, the valensixthtone~~ comma, in the 5-limit. In the 7-limit it tempers out 126/125 and 1029/1024, ~~supporting~~ [[~~Starling_temperaments#Valentine temperament|~~valentine ~~temperament~~]], and making for a good tuning for it and for starling temperament, the planar temperament tempering out 126/125. In the 11-limit the patent val tempers out 540/539 and the 108e val tempers out 121/120 ~~and~~ 176/175, supporting 11-limit valentine for which it is again a good tuning.

108edo is the smallest 12''n''-edo which offers a decent alternative fifth to 12edo's fifth, that is [[27edo]]'s superpyth fifth.
