2432/2431, the Blumeyer comma, is a 19-limit superparticular comma of about 0.71 cents. It is the amount by which a stack of 17/16 and 22/19 falls short of 16/13.
Etymology
In 2011, Douglas Blumeyer named the Blumeyer comma after himself.[1] There is no connection between his name and properties of the comma; he was simply in his early days working with microtonality, at Xenharmonic Praxis Summer Camp of that year, and excited to discover this magical-seeming interval featuring exactly one each of the teen primes, then further excited to find no record of anyone else interested in it. So he impulsively threw his name out at it, and used it extensively in his compositions in the following years.
