On the Covering Number of $U_{3} (q)$

Michael Epstein

The covering number, $σ (G)$ , of a finite, noncyclic group $G$ is the least positive integer $n$ such that $G$ is the union of $n$ proper subgroups. Here we investigate the covering…

The Covering Numbers of the McLaughlin Group and some Primitive Groups of Low Degree

Michael Epstein

A \emph{finite cover} of a group $G$ is a finite collection $C$ of proper subgroups of $G$ with the property that $⋃ C = G$ . A finite group admits a finit…
