I actually have a large infinite group that acts on my graph, although it is not clear (to me, at least) what the quotient of that action is, nor whether the image will be the entire automorphism group (although I suspect that it generally will be). It's also good to know, as Richard Stanley also pointed out in the comments, that although large automorphism group (often) leads to factorization of the adjacency polynomial, the converse need not hold. | |
