Abstract:The Steenrod problem asks: given a $G$-module, when does there exist a Moore space realizing the module? By using the equivariant Postnikov Tower, it is shown that a $\mathbb{Z} G$-module is $\mathbb{Z} G$-realizable if and only if it is $\mathbb{Z} H$-realizable for all $p$-Sylow subgroups $H$, for all primes $p\vert\vert G\vert$.
