80afdo (arithmetic frequency division of the octave), or 80odo (otonal division of the octave), divides the octave into 80 parts of 1/80 each. It is a superset of 79afdo and a subset of 81afdo. As a scale it may be known as mode 80 of the harmonic series or the Over-80 scale.
As a higher octave of 5afdo, 80afdo can be used as an over-5 scale in primodality.
