Its inversion is the "first septendecimal tritone," [[24_17|24/17]], and the interval that separates them is the small [[comma]] [[289_288|289/288]], about 6¢. This difference is usually negligible, and tempering out this comma allows the 600¢ half-octave to function as both septendecimal tritones. Thus, every even-numbered [[EDO]] system contains a close approximation to these intervals. 17/12 is the [[mediant]] between the two septimal tritones [[7_5|7/5]] and [[10_7|10/7]].
