Character expansiveness in finite groups

We say that a finite group $G$ is conjugacy expansive if for anynormal subset $S$ and any conjugacy class $C$ of $G$ the normalset $SC$ consists of at least as many conjugacy classes of $G$ as$S$ does. Halasi, Mar'oti, Sidki, Bezerra have shown that a groupis conjugacy expansive if and only if...
