* [[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 <math>G</math> is a non-cyclic group by an arbitrary [[finite group]], we can find two permutation representations <math>\varphi_1, \varphi_2</math> of <math>G</math> that are equivalent as linear representations but not as permutation representations.
