Аннотация
The paper presents a full description of idempotent elements of the semigroup of binary relations BX(D), which are defined by semilattices of the class Σ3(X, 8). For the case where X is a finite set and Z7 = Ø, we derive formulas for calculating the number of idempotent elements of the respective semigroup.
