On the Characterization of Sporadic Simple Groups by Codegrees

Mallory Dolorfino, Luke Martin, Zachary Slonim +2

Let $G$ be a finite group and $\mathrm{Irr}(G)$ the set of all irreducible complex characters of $G$. Define the codegree of $\chi \in \mathrm{Irr}(G)$ as $\mathrm{cod}(χ):=\frac{|G:\m…
