We list explicitly a minimal set of generators for the cohomology of an ele
mentary abelian p-group, V, of rank 1 or 2, as a module over the mod p Stee
nrod algebra, for an odd prime p. Following Singer, we then construct a tra
nsfer map to the vector space spanned by such generators, where V now has a
rbitrary rank, from the homology of the Steenrod algebra. We show that this
map takes images in the subspace of GL(V)-invariants and that it is an iso
morphism for V having rank 1 or 2.
