N2 - Let F be an arbitrary field, H be a subgroup of the symmetric group of degree m, Sm, λ be an irreducible F-valued character of H and dH λ be the generalizedmatrix function associated toH and λ. In this note we present some properties of the pairs (A, B) of m × m matrices over F that satisfy dH λ (AXB) = dH λ (X) for all X.We also describe the pairs (A, B) satisfying dH λ (AX) = dH λ (XB) for all X.
