 Apr 7 awarded Popular Question Oct 22 awarded Necromancer Apr 14 comment Combination of $k$ vertices from the $n$ vertices of $n$-sided regular polygon @GerryMyerson It's true, I have check it with program. You're so wise and virtuous! Jan 9 comment Is there any efficient progam or software to calculate the fractional chromatic number? @AlexanderKonovalov With no more than 100 vertices. Jan 9 comment Is there any efficient progam or software to calculate the fractional chromatic number? @ChrisGodsil Yeah, it is in theory.

Not all the isomorphism from the graph G to G itself is automorphism. Since automorphism preserving the edge–vertex connectivity.
