A class of bisimple, idempotent-generated congruence-free semigroups

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1981
SynopsisLet X be a set with infinite regular cardinality m. Within the full transformation semigroup ℑ(X) a subsemigroup Sm is described which is bisimple and idempotent-generated. Its minimum non-trivial homomorphic image has both these properties and is also congruence-free.
