Original Wikitext content:
16875/16384 is the 51.120 cent interval called the negri 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 negri temperament, which is closely associated with [[19edo]].
