@Math Lover OK, let me try to answer this question. But
I think your answer is pretty good and your upper bound is stronger than mine!

@MathLover If you've delete the answer, may I express your idea (the upper bound) in my answer?

@Anonymous +1 for your answer. btw an upper bound that shows OP + OQ + OR < 3 is sufficient to prove there are no integer solutions.
btw how do you conclude in your answer that OP + OP' < PQ?
