23edo has a very close approximation of [[11/7#Proximity with π/2|acoustic π/2]] on 15\23 and a very close approximation of [[acoustic phi]] on the step just above (16\23).

Not until [[72edo|72]] do we find a better EDO in terms of absolute error, and not until [[749edo|749]] do we find one in terms of relative error.
