The Baby Monster is the largest group with at most 2 irreducible characters with the same degree

Abstract We classify all finite groups such that all irreducible character degrees appear with multiplicity at most 2. As a consequence, we prove that the largest group with at most two irreducible characters of the same degree is the Baby Monster.
