64/55, the keenanismic subminor third, is 385/384 (4.5 cents) flatter than 7/6. It arises in 11-limit scales as the interval between 5/4 and 16/11, and between 11/8 and 8/5. On account of its close resemblance to 7/6, it can be stacked on top of a 5/4 major third as a means of creating one of the least dissonant among triads with a 16/11 subfifth as the outside interval.
