Finite groups of non-prime-power order with exactly four character codegrees

Yu Zeng, Mehdi Ghaffarzadeh, Mohsen Ghasemi +1

For an irreducible complex character $χ$ of a finite group $G$, the \emph{codegree} of $χ$ is defined as the ratio $|G : \ker(χ)| / χ(1)$, where $\ker(χ)$ represents the…

Character degrees of extensions of the Suzuki groups $^{2} B_{2} (q^{2})$

Mehdi Ghaffarzadeh

Let $S$ be a Suzuki group $^{2} B_{2} (q^{2})$ , where $q^{2} = 2^{2 f + 1}$ , $f ⩾ 1$ . In this paper, we determine the degrees of the ordinary complex irreducible characters of every group…
