Oppermann's Conjecture concerns the distribution of.
It was first suggested in 1877, and has not been proved or disproved since then.
The conjecture states that : for every integer x > 1, there is at least one prime number between x(x − 1) and x2, and at least another prime between x2 and x(x + 1).
Put non-mathematically “Is every pair of a square number and a pronic number (both greater than one) separated by at least one prime?”
