Original Wikitext content:
Superpartient numbers are ratios of the form p/q, where p and q are relatively prime (so that the fraction is reduced to lowest terms), and p - q is greater than 1. In ancient Greece they were called Epimeric (epimerēs) ratios, which is literally translated as "above a part." These ratios were considered to be inferior to Epimoric ratios. All epimeric ratios can be constructed as combinations of [[superparticular|superparticular numbers]]. For example, 9/5 is 3/2 × 6/5. In ancient Greece, fractions like 3/1 and 7/1 were not considered to be epimeric ratios because of the additional restriction that [[Harmonic|multiples of the fundamental]] cannot be epimeric. When considering ratios, and particularly when they are ratios for [[comma|commas]], it can be useful to introduce the notion of the degree of epimericity. In terms of p/q reduced to lowest terms it is p - q. An epimoric ratio has degree 1, the 7-limit comma 245/243 degree 2, the 5-limit comma 128/125 degree 3, and so forth. [[http://en.wikipedia.org/wiki/St%C3%B8rmer's_theorem|Størmer's theorem]] can be extended to the claim that for each prime limit p and each degree of epimoricity n, there are only finitely many p-limit ratios with degree of epimoricity less than or equal to n.
