This is a ,key, first step in coming up with a version of Schur-Weyl du-ality for this group. The ,centralizer, of the action of A n on k-fold tensor copies of its permutation representation should be a super-algebra of the partition algebra.

Proposition 2.1.3 (,Double centralizer theorem,). Let Ebe a finite-dimensional vector space. Suppose A⊂End(E) is a semisimple subalgebra. (1) A= EndB(E). (2) Bis semisimple. (3) As a representation of A×B, Edecomposes as E= M i∈I Vi ⊗Wi, where the Vi are all of the irreducible A-modules and the Wi are all of the irreducible B-modules.

appeared along with Jannsen's ,theorem, that the category of motives is abelian semi-simple if and only if the equivalence relation is numerical equivalence. The proof of this ,theorem, is beautiful, simple and short. (The main tool is the ,double,-,centralizer theorem,.) I will try to do it justice in my lectures.
