2.7. Young subgroups, wreath products, Sylow p-subgroups of Sn. Let n ∈ Z+ . (a) For a partition, or, more generally, a composition λ = (λ1, . . . , λk) of n, we denote by Sλ = Sλ1 × · · · × Sλk the corresponding standard Young subgroup of Sn. (b) Let G be any finite group, and let H 6 Sn. We have the wreath product G ≀ H := {(g1, . . . , gn; σ) : g1, . . . , gn ∈ G, σ ∈ H}, whose multiplication is given by the trivial F Sα-module F (α) to Sk ≀ Sα. Moreover, if k is odd then s\gn(k) s\gn(k)⊗βt ∼= sgn(Sk ≀ Sβ) (see Remark 3.11). Now set [2] M. Broué, On Scott modules and p-permutation modules: an approach through the Brauer morphism, Proc. Amer.
