The error message is (I suppose) `No method found'. This means that GAP
(4.2) is not able to construct semidirect products of matrix groups in
This functionality will be updated in the coming release 4.3.
(If you need, I can send you a description how to construct a group
isomorphic to this semidirect product in 4.2.)
