[sound info]
The 5-limit interval 135/128, about 92.2 cents in size, is called the pelogic comma, major limma or major chroma. It is a syntonic comma away from the pythagorean major semitone 2187/2048, and so is tuned justly in 1/7 comma meantone. Flattening by another syntonic comma reaches the even simpler 25/24.
As a comma it represents the difference between three perfect fourths and a just major third (plus an octave).
