Indexed interval notation is a notation for just intonation devised by CompactStar.
Intervals are represented by a normal interval category (like minor 3rd, perfect 4th or etc.) and an index. The index is 1 for the simplest (with respect Tenney height) interval in a category, 2 for the second-simplest, 3 for the third-simplest and so on. For example, 6/5 is the 1st minor 3rd (1m3) and 7/6 is the 2nd minor 3rd (2m3). Note names work the same way, using A4 as the reference pitch, so the C which is 6/5 above A (528 Hz) is notated as 1C.
