====== Brocard's conjecture ====== Brocard's conjecture asserts that there are at least four prime numbers between (//pn//)2 and (//pn+1)2, where //pn is the //n//th prime number, for every //n// ≥ 2. It was first suggested by French mathematician Henri Brocard in the late 19th century. As yet, it has neither been proved or disproved.
