Original Wikitext content:
Superparticular numbers are ratios of the form (n+1)/n, or 1+1/n. In ancient Greece they were known as Epimoric (επιμοριοσ, epimorios) ratios, which is literally translated as "above a part." These ratios have some peculiar properties: * The difference tone of the dyad is also the virtual fundamental. * The first 6 such ratios ([[3_2|3/2]], [[4_3|4/3]], [[5_4|5/4]], [[6_5|6/5]], [[7_6|7/6]], [[8_7|8/7]]) are notable [[harmonic entropy]] minima. * The difference between two successive epimoric ratios is always an epimoric ratio. * The sum of two successive epimoric ratios is either an epimoric ratio or an epimeric ratio. * Every epimoric ratio can be split into two or more smaller epimoric ratios via the arithmetic mean. Curiously enough, the ancient Greeks did not consider 2/1 to be superparticular because it is a harmonic. <span style="background-color: initial;">[[http://en.wikipedia.org/wiki/Superparticular_number]]</span>
