'''5ED5/4''' is the [[Equal-step tuning|equal division]] of the [[5/4|just major third]] into five parts of 77.2627 [[cent|cents]] each, corresponding to every second step of [[31edo]]. It is related to [[Carlos Alpha]] and the 7-limit temperaments which temper out 2100875/2097152 (including the [[Breedsmic temperaments|tertiaseptal temperament]] and the [[Starling temperaments|valentine temperament]]).
