This is because the operations are based on the internal vertex ids and not on the vertex names. You can do two things. One is that you permute the vertices in your graphs, so that the vertex id match, see permute.vertices() this. The other is that you take the code from http://lists.gnu.org/archive/html/igraph-help/2009-10/msg00087.html Best, Gabor > I tried getting around this all day but couldn't come up with the resultant > graph.
