On groups with square-free gcd of character degree and codegree

Karam Aldahleh, Alan Kappler, Neil Makur +1

Let $G$ be a finite group and $χ$ be an irreducible character of $G$ . The codegree of $χ$ is defined as $χ^{c} (1) = \frac{∣ G : k e r χ ∣}{χ ( 1 )}$ . In a paper by Gao, Wang, and Chen, it was…
