* [[Symmetric group is not subsetAnalogue of Brauer's permutation lemma fails to hold for every non-conjugacy-closed in general linear cyclic finite group]]: In particular, in formulation (4), we ''cannot'' replace If $G$ is a non-cyclic group by an arbitrary [[finite group]], we can find two permutation representations $\varphi_1, \varphi_2$ of $G$ that are equivalent as linear representations but not as permutation representations.
