224edo is a very strong [[13-limit]] system. It is the twelfth [[ | 224edo is a very strong [[13-limit]] system. It is the twelfth [[zeta integral edo]] and is the second-smallest edo after [[87edo|87]] to approximate all of the first 16 harmonics of the harmonic series with [[minimal consistent EDOs|no greater than 25%]] relative error. | ||
