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