Web(We can say this with certainty because the largest gap between any primes up to 18 digits is only 1442; this gap happens between the primes 804212830686677669 and 804212830686679111. The interval (n 2, (n+1) 2) is wider than 1442 when n > 720, so Legendre's conjecture seems a safe bet, up to 18-digit primes.) Back to statement (B).
