Dear Jitender Kumar, Can you please explain what you mean by `see list or Sizes of SemigroupHomomorphismByImagesOfGens'? SemigroupHomomorphismByImagesOfGens(S, S, GeneratorsOfSemigroup(S)) returns the identity homomorphism from the semigroup S to itself. I'm not sure what the size of a homomorphism would be, or what you would expect to be returned by List(J). If you can explain, then maybe I can answer.
In a separate note, the Monoid package has been replaces by the Citrus package in GAP 4.5 and I strongly suggest that you use the latest version of Citrus instead of Monoid.
