Honestly, I have been looking for an a **finite Quasicommutative semigroup** by surfing the web, but I could't. May I ask here to give me an example for such this kind of semigroup. I tried to built one of them by using GAP, but it fails. Thank you so much. I am new to it.



Asking about a quasicommutative semigroup
The simple examples are Hamiltonian groups. Then you can construct Clifford semigroups from them.
