Fun and games with the Steenrod algebra

Abstract: The mod 2 Steenrod algebra is an important tool in unstable and stable homotopy theory but it is also interesting as a purely algebraic gadget. I will briefly review its algebraic structure and that of some important finite subHopf algebras. Then I will discuss some realisability questions for modules, ranging from classical examples to modules over the E-infinity ring spectra kO and tmf localised at 2. I hope this talk will be accessible to beginners and also have some things to interest experts.
