It is well known that the free group on a non-empty set can be totally ordered and, further, that each compatible latttice ordering on a free group is a total ordering. On the other hand, SaitΓ΄ has shown that no non-trivial free inverse semigroup can be totally ordered. In this note we show, however
## Given a permutation x n β S. Various permutability conditions were considered for special classes of permutations. We define the permutability class of a semigroup S to be the infinite sequence The aim of this paper is to give a description of such sequences, which generalizes a number of old
