The smallest [[equal division of the octave]] which is [[consistent]] in the 9-odd-limit is [[5edo]]; that which is distinctly consistent in the same is [[41edo]]. The {{w|natural density|density}} of edos consistent in the 9-odd-limit is 1/4<ref group="note">Provable in a similar method to the one for the 5-odd-limit.</ref>.
