Dear GAP-Forum, Due to a slight change in the functionality of `StabChainBaseStrongGenerators' in GAP 4.4.5, there is a problem (under Unix) when GRAPE/nauty computes a trivial automorphism group for a graph (this leads to a break-loop being entered, not incorrect results being returned). This problem may be fixed by replacing the file $GAPROOT/pkg/grape/lib/grape.g by the file at http://www.maths.qmul.ac.uk/~leonard/grape/grape.g Users of the Design 1.1 package under a Unix version of GAP 4.4.5 should also make this change to GRAPE.
I am grateful to Akihide Hanaki for pointing out this problem. Regards, Leonard _______________________________________________ Forum mailing list [email protected] http://mail.gap-system.org/mailman/listinfo/forum
