{{EDO intro|8269}} It is both a [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak and zeta integral edo]], which has to do with the fact that it is a very strong 19- and 23-limit division.

Template:EDO intro It is both a zeta peak and zeta integral edo, which has to do with the fact that it is a very strong 19- and 23-limit division. It has a lower 19-limit and a lower 23-limit relative error than any smaller division, a lower 19-limit TE loglfat badness than any smaller division, and a lower 23-limit logflat badness than any excepting 311, 581, 1578 and 2460.
