Theory
288edo is the least common multiple of 72edo and 96edo, which are historically notable. 72edo has been used in Byzantine chanting, has been theoreticized by Alois Haba and Ivan Wyschnegradsky, and has been used by jazz musician Joe Maneri. 96edo has been used by Julian Carrillo. This description as a corollary also fits every edo that is a multiple of 288, like 576 or 2016.
