Shum [9] in his work on systems of semigroups and its application in constructing generalized cryptogroups introduced the concepts of Green ???????? on ? ? ????????? semigroups by using the generalized strong semilattice of semigroups, he also used a generalization of a well-known result of fountain on super-abundant semigroup to show that ? ? ???????????? is regular ? ? ? ?????????? if and only if it is an ?? ? ??????? ??????????? of completely ? ? ??????? semigroups. In this paper further explanation were made and proves of some lemmas, additional characteristics of the ? ? ????????? semigroup is proved. Lastly the concepts of ? ? ? ???????? semigroup in group with examples is given.
