25ed7 as a generator
25ed7 can also be thought of as a generator of the 23-limit temperament which tempers out 169/168, 176/175, 208/207, 221/220, 247/245, 256/255, and 361/360, which is a cluster temperament with nine clusters of notes in an octave. This temperament is supported by 9edo, 71edo (using 71d val), 80edo, and 89edo among others.
