2601/2600 is a 17-limit (also subgroup) superparticular comma measuring about 0.67 cents. It may be properly described as the septendecimal sixth-tones comma, since it is the difference between 51/50 and 52/51, the two 17-limit sixth-tones. Another prominent identity is the little gap between 18/13 and a stack of two 20/17's.

In terms of commas, it is the difference between the following pairs:


Tempering out this comma results in 26/25 being split into two equal parts, each representing 51/50~52/51, and enables the related essentially tempered chords.
