You can put this solution on YOUR website! .
I think that your post (the problem condition in the post) is INCORRECT, since it is INCOMPLETE.
To be complete, it should provide all THREE in-pair intersection quantities.
It could be a nice problem, and had it be posted correctly, I would give you a brilliant solution.
But for a defective problem, I can not provide a solution.
