Dear Forum, Abdulsatar Al-Juburie asked:
> Let X be a finite set and let x be a fixed element of X. > Is there any function in GAP that generates all subsets of X that contains x. Provided that the set X is small enough such that the desired list of subsets fits into the memory of the computer, the following statement will do what you want: List(Combinations(Difference(X,[x])),Y->Union(Y,[x])); Hope this helps, Stefan Kohl _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
