16875/16384 is the 51.120 cent interval called the negri [[Comma|comma]] or double augmentation diesis. It is the amount by which four major thirds exceed three fourths, that is, (5/4)^4/(4/3)^3, and is also the amount by which three [[16/15|diatonic semitones]] fall short of a major third, that is, (5/4)/(16/15)^3. Tempering it out leads to [[5-limit|5-limit]] [[Negri|negri temperament]], which is closely associated with [[19edo|19edo]].
