'''256/255''', the '''septendecimal kleisma''', '''charisma''', '''char comma''' or '''octave-reduced 255th subharmonic''' is a [[small comma|small]] [[17-limit]] [[superparticular]] comma about 6.8 [[cent]]s in size. It is the difference between [[16/15]] (the classical diatonic semitone) and [[17/16]] (the large septendecimal semitone), the difference between an Archagall fifth ([[128/75]] and a just perfect fifth ([[3/2]]), and the amount by which a stack consisting of [[15/8]] and 17/16 falls short of an [[octave]]. It is a [[Mersenne comma]].
