[GAP Forum] Wreath Product for Monoids

Dear Forum, Dear Jan-Philip W"achter,

The GAP library only provides methods to construct wreath products of (finite) groups. It would be possible to install methods for monoids using InstallOtherMethod, but I am not aware of such code. Your bet bet might be to simply construct the wreath product ``by hand''.
