21edo has the very close approximation of logarithmic π (3\21) from [[7edo]], and a very close [[Logarithmic phi|logarithmic ϕ]] (13\21). (octave-reduced equivalences) | |||
Not until [[128edo|128]] do we find a better EDO in terms of absolute error on these two intervals, and not until [[212edo|212]] do we find one in terms of relative error. | Not until [[128edo|128]] do we find a better EDO in terms of absolute error on these two intervals, and not until [[212edo|212]] do we find one in terms of relative error. | ||
