The action of the symmetric group $S_{mn}$ on set partitions of sets of size $mn$ into $n$ sets of size $m$ gives rise to a permutation module called the Foulkes module, $H$. Structurally, very little is known about Foulkes modules, even over $\mathbb{C}$. In this talk, we will focus on $H{(4^n)}$ and we will see that it is possible to obtain a lot of new structural information by using induction and restriction of modules as the main tools.

This talk is part of the Junior Algebra and Number Theory seminar series.
