Abstract: Let be the cohomology of the elementary abelian group ( factors). The Steenrod algebra acts on according to well-known rules. If denotes the augmentation ideal, then we are interested in determining the image of the action : the space of elements in that are hit by positive dimensional Steenrod squares. The problem is motivated by applications to cobordism theory [P1] and the homology of the Steenrod algebra [S]. Our main result, which generalizes work of Wood [W], identifies a new class of hit monomials.
