Combinatorial methods are employed to study the double cosets of the symmetric group S n with respect to Young subgroups H and K . The current paper develops a correspondence between these double cosets and certain lists of integers . This approach leads naturally to an algorithm for computing the n

We study the number of homomorphisms from a finite group to a general linear group over a finite field. In particular, we give a generating function of such numbers. Then the Rogers-Ramanujan identities are applicable.
