Re: Need Graph Isomorphism Algorithm De-bunked

I ran the second algorithm[1] on all simply connected graphs of 8
nodes or fewer (with bidirectional edges only and with no edge from
a node to itself, restrictions which make it feasible to go up to
8 nodes).

Nodes Distinct graphs
2 1
3 2
4 6
5 21
6 112
7 853
8 10897 and counting (Give it another 10 or 20 hours.)

So far so good

It finished counting, and got 11117 for 8 nodes. So much for the easy counterexample.
