Dear Alper Odabaş,

Here is the code (actually, cosmetically modified one by Willem de 
Graaf) which supposed to construct semidirect product of Lie algebras: 
http://justpasha.org/unixcrap/gap/semidirect.gap . I used it almost two 
years ago when playing with GAP, so don't remember much details, but it 
worked for me then.

Cheers, Pasha.
