Dear forum, Let H be an abelian group, and f:HxH-->F_q* a 2-cocycle (where F_q* are the unities of the finite filed of q elements), if T:H-->H is an automorphism the map f^T(a,b):=f(T(a),T(b)) is also a 2-cocycle. How can I use GAP in order to decided if f and f^T are cohomologous and to construct an explicit the coboundady?
