if your graph is highly irregular, the degree of the minimal polynomial will be not too far from the number of vertices, and so you'd be really out of luck. How do you obtain your graphs? Do they have any symmetry? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
