The nth Prime Page will now find any of the first 2.623˙10^{15} primes or
π(x) for x up to 10^{17}. If n is greater than or equal to 118, then the interval n to 4n/3 inclusive contains a prime number of each of the forms 4n + 1, 4n  1, 6n + 1 and 6n  1. [Wells] 118 is the smallest even number not differing by one or a prime number from one of its prime neighbors. [Wagler] According to Rohrbach and Weis, p(n+1)p(n)1 < (1/13)p(n) for n > 118. [Post]
