'''17303/17280''', the '''tridecimal eighth-octave comma''', is an unnoticable comma that is the difference between three [[12/11]] neutral seconds and a [[13/10]] semisixth, and is also the interval separating [[1331/1296]] from the simpler [[40/39]]. It is tempered out in low EDOs that are a multiple of 8, along with [[214990848/214358881]] and [[ | '''17303/17280''', the '''tridecimal eighth-octave comma''', is an unnoticable comma that is the difference between three [[12/11]] neutral seconds and a [[13/10]] semisixth, and is also the interval separating [[1331/1296]] from the simpler [[40/39]].
