I've implemented all the suggestions, but I've left the conversations for the less trivial comments open for you to respond in the case of me doing something wrong. |

Title.
Perhaps someone with more knowledge of groups has a better way of computing the disjoint automorphisms. My approach might be a little naive. So, I am open to suggestions. However, the current method should at least work.
I also added the Petersen graph (@danteluber) and the Clebsch graph, as these are good examples of how the function behaves.
FYI: Disjoint automorphisms are important for computing the quantum symmetries of graphs, as their existence is a sufficient but not necessary criterion for a graph to have quantum symmetries.
