In [3] it is shown that any finitely presented semigroup S is embedded into an inefficient semigroup, namely, the semigroup S∪SLn where SLn is the free semilattice of rank n. Let S be a finite semigroup. If x ∈ S, since S is periodic there exists ∃m, n ∈ N such that xm = xn.	cache/ejpam-1809.pdf	txt/ejpam-1809.txt
