11afdo (arithmetic frequency division of the octave), or 11odo (otonal division of the octave), divides the octave into eleven parts of 1/11 each. As a scale it may be known as mode 11 of the harmonic series or the Over-11 scale. As 11 is a small odd number, this AFDO does not contain a perfect fifth above the root, although it does contain a 16/11 subfifth and a 17/11 ultrafifth / inframinor sixth.
