The counterschisma is a 5-limit unnoticeable comma measuring about 1.66 cents. While the schisma is the difference between the Pythagorean comma and the syntonic comma, the counterschisma, in contrast, is the difference between the 41-comma and the syntonic comma, or equivalently stated, the difference between the 53-comma and the schisma, making the temperament part of the Schismic-Mercator equivalence continuum.
