Abstract
We classify modular fusion categories up to braided equivalence with less than four distinct twists of simple objects by observing that under this assumption, for each positive integer , there are finitely many modular fusion categories of Frobenius-Schur exponent up to braided equivalence whose twists are a proper subset of the roots of unity.
