The '''septendecima''' ([[monzo]]: {{monzo| -52 -17 34 }}) is a [[5-limit]] [[unnoticeable comma]]. It represents the difference between a stack of seventeen [[25/24]] intervals and one octave, and tempering it out means that [[25/24 equal-step tuning]] is equated with [[17edo]]. Therefore, a temperament must be divisible by 17 in order to temper out this comma, any edo such as [[311edo]], which isn't a multiple of 17 cannot be tempering out the 25/24 kleisma.

The septendecima (monzo: [-52 -17 34) is a 5-limit unnoticeable comma. It represents the difference between a stack of seventeen 25/24 intervals and one octave, and tempering it out means that 25/24 equal-step tuning is equated with 17edo. Therefore, a temperament must be divisible by 17 in order to temper out this comma, any edo such as 311edo, which isn't a multiple of 17 cannot be tempering out the 25/24 kleisma. The temperament which tempers out only this comma is 5-limit chlorine.
