The Cohomology Alegbra of a Subalgebra of the Steenrod Algebra

We compute the cohomology algebra of P(1), the subalgebra of the Steenrod
algebra generated by P^1 and P^p. This completes a partial result given by
Arunas Liulevicius in 1962 and provides explicit representatives in the cobar
costruction for all but one of the algebra generators.
