32afdo (arithmetic frequency division of the octave), or 32odo (otonal division of the octave), divides the octave into 32 parts of 1/32 each. It is a superset of 31afdo and a subset of 33afdo. As a scale it may be known as mode 32 of the harmonic series or the Over-32 scale.
The smallest edo that maintains 25% or lower relative error on all intervals of 32afdo is 3159811edo.
