Abstract: | It is shown that properties of the structure of a finite semigroup S such as the order of the set ofJ of S and the existence of normal subsemigroups may be deduced from the knowledge of the characters of the irreducible representations
of S. The character table of the full transformation semigroup T4 of a four-element set is given. |
