The mod 2 Steenrod algebra A2 can be defined as the quotient of the mod 2 Leibniz–Hopf algebra F2 by the Adem relations. Dually, the mod 2 dual Steenrod algebra A2∗ can be thought of as a sub-Hopf algebra of the mod 2 dual Leibniz–Hopf algebra F2∗. We study A2∗ and F2∗ from this viewpoint and give generalisations of some classical results in the literature.
