In [[13-limit]] [[just intonation]], '''55/39''' is the '''smaller ~~tridecimal~~ tritone''', measuring about 595.1¢. It is [[275/273]] (gassorma, about 12.6¢) sharp of [[7/5]], and is the interval between [[13/11]] and [[5/3]]. Its inversion is the larger ~~tridecimal~~ tritone, [[78/55]], and the interval that separates them is the small [[comma]] [[3042/3025]], about 9.7¢. This difference can be negligible, and tempering out this comma allows the 600¢ half-octave to function as both ~~tridecimal~~ tritones. Thus, every even-numbered [[EDO]] system contains a close approximation to these intervals.
