p.s. I haven’t found a source for the Devil’s book (or even, more modestly, for the claim the Book exists :-) I don’t think I made it up myself, but who knows...

Thanks, Jim! I certainly agree that multiple proofs deserve Bookhood
(and
some clearly don’t). This is a great example, especially given your comments about how each proof has different power to generalize.
I think you should do a column sometime on the Devil’s book — the book of mathematical truths that are easy to state, but which have no proof in God's book. Perhaps the 4-color theorem is one of these…
