For algebraic objects, say for groups $ N,K$ and algebra $A$, if we have the semidirect product of a semidirect product, $(A \rtimes_{\gamma} N ) \rtimes_{\theta} K$, are there conditions that would allow us to collapse this to a single semidirect product over $A$?

4$\begingroup$ I can think of some very trivial conditions which probably don't interest you. Probably if you say more about your situation you can get better answers. $\endgroup$– Fernando MuroCommented Mar 4, 2016 at 7:12
