Abstrakt: In this paper we give a full description of regular elements of the semigroup that are defined by semilattices of the class, when Z ∩ Z ≠ ∅. Formulas are derived by means of which the number of regular elements of the semigroup is calculated when it is a finite set. [ABSTRACT FROM AUTHOR]
