Lefts and rights notation is a notation for just intonation primarily developed by CompactStar.
Explanation
All just intervals are indicated by a direction, which is a sequence of lefts and rights, and a degree. The degree is calculated by adding 1 to the 7edo patent val mapping of a ratio. The "default" direction, with no lefts or rights is central (C). If k is a degree, the central k-th is defined as the simplest (with respect to Tenney height) just k-th that is within 20 cents of (k-1)\7.
Examples
Below are some examples of lefts and rights notation for 11-odd-limit intervals:
