Let G denote the finite general linear group GLn(Fq) over the finite field with q elements. Associated to each partition λ of n, there is an irreducible unipotent complex character χλ of G. The degree of χλ is a polynomial in q given by Green’s hook formula [8, p.444]; the polynomial is monic of degree b(λ′) where λ′ is the transpose of λ and, for a partition μ = (m1 ≥ m2 ≥ · · · ≥ mh > 0) of n, b(μ) denotes n(n+1) 2 − ∑h i=1 imi. An easy consequence of Green’s formula is that
