Let the mod 2 Steenrod algebra, , and the general linear group, GL k = GL k 2 , act on P k = 2 x 1 x k with deg x i = 1 in the usual manner. We prove that, for a family of some rather small subgroups G of GL k , every element of positive degree in the invariant algebra P G k is hit by in P k . In ot
