For debugging hints type ?Recovery from NoMethodFound > [...] The function `PossibleClassFusions' is not defined for the case that one argument is a Brauer table and the other is an ordinary table, see the GAP Reference Manual.

PossibleClassFusions( c1 mod 11, c2 mod 11 ); All the best, Thomas Breuer _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
