Dear forum, Is there a way to define a central product in GAP, and how do we define the common central factor in this function? For example we want to define G:=Q8.K(the central product), where, Q8 is the quaternion group of order 8 presented as ; <a,b:a^4=1,b^2=a^2,bab^-1=a^-1> and K=<x,y:x^4=y^4=1,yxy^-1=x^-1> with te common central factor being x^2y^2.
Thanks in advance, -- *Sümeyra Bedir* _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
