Specht module

Specht modules are some very nice [S n]\mathbb{Z}[S_n] modules which are irreducible? after base change to \mathbb{Q}. Over a field of characteristic pp, where pn!p \mid n!, the base changes are not irreducible, but every irreducible module appears as the cosocle? of a Specht module.
