Abstract
We consider an arbitrary irreducible representation of a symmetric group S4m that has a B2m-invariant and a B2m-antiinvariant vector, where B2m is a hyperoctahedral subgroup of S4m. The main result is an expression for a matrix element corresponding to these two vectors in terms of an irreducible character of the symmetric group Sm.
