'''96889010407/68719476736 | '''96889010407/68719476736''', called the '''dilemma''' is a "comma" of almost 600 cents. It forms the amount by which thirteen [[7/4]]<nowiki/>s exceeds ten [[2/1|octaves]], and may be described as ''13-fold 7th harmonic tritone''. It is called the dilemma after forced moral dilemmas in interactive fiction, and after its location almost perfectly halfway between two octaves (it is one of the lowest [[Circular temperament|circular]] commas to do this). | ||

(If 7/4 is represented by 11\13 instead, thus tempering out [[137438953472/96889010407]], it leads to the [[antidilemmic]] or tsuchi temperament). | ||
