报告摘要  Abstract

A semigroup is regular if every element has a von Neumann inverse. Those permutation groups having the property that the semigroup generated by the group together with any non-permutation of the domain is regular, have been classified. Currently this is being extended by restricting the non-permutation to have given rank, or to have a given image.
