| The known theory for an oid T shows how to find a subset T of ?T, which is a compact right topological semigroup [I]. The success of the methods in [2] for obtaining properties of-T has prompted us to see how successful they would be in another context. Thus we find (Theorem 4.8) that T cont ains copies of free semigroups on 2? generators, is an immediate consequence of the stronger result and that it contains a cancellative subsemigroup (Theorem 4.7). Also obtained is a new proof of the known result in [6] that T contains 2? idempotents | ||
