I'm looking for a way to check if some graphs are perfect. GAP seems to be like the best way to do it, especially because I'm trying to do some things with groups at the same time. However, I haven't seen any function within GAP which would check perfectness of a graph. Does GAP have any such function?
I am familiar with the package GRAPE, as well as with AGT and Digraphs packages, but none of them seems to have this function built-in. Also, I am aware that GRAPE contains CliqueNumber and ChromaticNumber functions, and that I could use these two to check perfectness with a function of my own, but I'm still curious if that would be a necessary thing to do.
