comment Bourbaki's definition of semidirect product
But doesn't the definition of the external semidirect product work with any homomorphism $K \to Aut(H)$? There is no requirement stated that the automorphisms of $H$ mapped to must be given by conjugation by some element of $G$, but it just turns out that way, so how does this work?

comment When can a homomorphism be determined entirely by its generators
Hi @Lee Mosher, do you have a reference in a text where this statement can be found? Thanks
