RST notation is a notation mainly for just intonation that was devised by CompactStar. It is an extension of 3-limit chain-of-fifths notation where prefixes are added to convey higher-limit commatic alterations. The prefixes used are "ruper-"/"rub-" for the 5-limit formal comma 81/80, "super-"/"sub-" for the 7-limit formal comma 64/63, "tuper-"/"tub-" for the 11-limit formal comma 33/32, etc., going through a shifted version of the alphabet (RSTUVWXYZABCDEFGHIJKLMNOPQ), which is a generalization of super-/sub- for 64/63.
