And finally gives up admitting it is a counterexample. Even saying "holy shit". That's what any human expert would do: presented with an extremely improbable fact, it would verify it, then in disbelief verify it again, then change method, then try yet another one, checking its understanding of the problem itself... and finally concede. Because this is what intelligence looks like- understanding the problem, its relevance, its context, self-doubting if the solution looks too simple to be true, double-checking all calculations and trying different approaches, etc.
