The '''tricot comma''', with [[monzo]] {{monzo| 39 -29 3 }}, is an [[unnoticeable comma|unnoticeable]] [[5-limit]] [[comma]] measuring about 2.2 [[cent]]s. It is the difference between a stack of three [[schisma]]s and the [[53-comma]], making it part of the [[Schismic-Mercator equivalence continuum]]. In addition, it is the difference between a stack of three [[10/9]] intervals and a stack of twenty-three [[3/2]] perfect fifths octave-reduced.
