-If we do not temper out this interval and instead use it as an identity of some sort, it serves as the period in the [[chromium]] temperament, where it is mapped to 1/24th of the octave. Thus [[Eliora]] proposes the name ''chromium quartertone''.
+/243 is very close to one step of [[24edo]], which is the quarter tone that is exactly the half of [[12edo]] semitone. Therefore, if 250/243 is not tempered and instead is treated as an identity where it is equated with 1/24th of the octave, it serves as the period in the [[chromium]] temperament. (However, note that 24edo itself maps 250/243 inconsistently, and so chromium temperament starts at [[72edo]].) Thus in the framework of this temperament and the tuning systems associated with it, [[Eliora]] proposes the name ''chromium quartertone''.
