====== Oppermann's conjecture ====== //Oppermann's Conjecture// concerns the distribution of [[content:mathematics:prime_numbers]]. 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 //x//2, and at least another prime between //x//2 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?"// See : [[https://en.wikipedia.org/wiki/Oppermann%27s_conjecture|Wikipedia]] ---- Also see : [[content:mathematics:legendre_conjecture]]
