 More generally, we have the decomposition of the tensor product as formula_24-bimodule

where formula_26 is the Specht module indexed by λ. Schur functors can also be used to describe the coordinate ring of certain flag varieties.For two Young diagrams λ and μ consider the composition of the corresponding Schur functors Sλ(Sμ(-)).This composition is called a plethysm of λ and μ.
