Abstract A semigroup is called an epigroup if some power of each element lies in a subgroup. Under the universal of epigroups, the aim of the paper is devoted to presenting elements in the groupoid together with the multiplication of Malcev products generated by classes of completely simple semigroups, nil-semigroups and semilattices. The information about the set inclusion relations among them is also provided.

在某些类外群的 Malcev 积上，我

摘要 如果每个元素的某个幂位于子群中，则半群称为外群。在外群的普遍性下，本文的目的是致力于将群状中的元素与完全简单半群、零半群和半格类生成的马尔切夫乘积的乘法一起呈现。还提供了关于它们之间的集合包含关系的信息。
