Let Pk be the graded polynomial algebra \(\mathbb {F}_{2}[x_{1},x_{2},{\ldots } ,x_{k}]\) over the prime field of two elements, \(\mathbb {F}_{2}\), with the degree of each xi being 1. We study the hit problem, set up by Frank Peterson, of finding a minimal set of generators for Pk as a module over the mod-2 Steenrod algebra, \(\mathcal {A}\). In this paper, we explicitly determine a minimal set of \(\mathcal {A}\)-generators for Pk in the case k = 5 and the degree 4(2d−1) with d an arbitrary positive integer.
