论文摘要
有限的组$ g $的不冗余封面是一组适当的子群，其联合为$ g $，并且不包含较小的子覆盖物。我们对有限的群体进行了分类，这些群体恰好具有两个不冗余的封面，从而对布罗迪的一个问题发起了答案，布罗迪将有限的群体分类为一个不redrectuctionlaction的封面。
An irredundant cover of a finite group $G$ is a collection of proper subgroups whose union is $G$ and which contains no smaller subcover. We classify finite groups which possess exactly two irredundant covers, thereby initiating an answer to a question of Brodie, who classified finite groups with one irredundant cover.
