61/32, the octave-reduced 61st harmonic. It is sharp of the Pythagorean major seventh (243/128) by 244/243. Being the octave complement of the harry minor semitone 64/61, it can also be used as a generator for harry and tritikleismic.

In addition, the convergent chain of edos of representing it is 14, 29, 101, 130, 231. These are notable tuning systems in their own way, and they can be used to introduce 61-limit harmony into lower-limit music.
