Hi CURED. I'm not 100% sure on the Close for duplicate policy, but a new one has just popped up:
https://math.stackexchange.com/questions/4231540/how-to-find-the-largest-delta#comment8790868_4231540
is a duplicate for https://math.stackexchange.com/questions/4229749/finding-delta-based-on-given-value-of-epsilon
Though the asker gets a different result.

$$ x\ R \ y \iff x-y \ \text{is a prime number} $$
$ \ \bullet \text{show R is not an equvalence relation}$
$ \ \bullet \text{find the smallest equivalence relation $Q$ such that}\ R \subset Q$
hint:$x\ Q\ (x+1)$
, the first point is easy, but I can't come up with a relation $Q$.
