Find (up to isomorphism) all self-complementary graphs of order 5. Be sure to justify your answer. (Hint: what does the degree sequence of a self-complementary graph look like?)
I can't seem to figure out the hint. Can anyone explain to me what this degree sequence would look like? Thanks.
P.S. Thanks to ThePerfectHacker for your help on my last question. n(n-1)/2 seemed to have slipped my mind. That helped a lot. :)
