Dear forum,
I was considering graphs again, and I had another question about the
package GRAPE, in particular about the command "Bicomponents".
If I first do:
LoadPackage("grape");
trivialaction := function(x,g) return x; end;
n:=6;s:=[1000..1000+n-1];
graph:=Graph(Group(()), s, trivialaction, function(x,y) return (((x-y)
mod n) in [n-1,1]); end,true);
then the output of the following code:
Vertices(graph);Bicomponents(graph);
is:
[ 1 .. 6 ]
[ [ 1, 3, 5 ], [ 2, 4, 6 ] ]
This is of course correct, but my original graph had vertices
[1000..1000+n-1], and I would like to have my bicomponents in terms of
those vertices. Is that possible?
Thanks,
Frédéric
