Table of Known Maximal Gaps between Primes
primes.utm.edu › notes › GapsTableIn the following table we list the maximal gaps through 1355. These are the first occurrences of gaps of at least this length . For example, there is a gap of 879 composites after the prime 277900416100927. This is the first occurrence of a gap of this length, but still is not a maximal gap since 905 composites follow the smaller prime
Prime gap - Wikipedia
https://en.wikipedia.org/wiki/Prime_gapUsually the ratio of gn / ln(pn) is called the merit of the gap gn . As of September 2017 , the largest known prime gap with identified probable prime gap ends has length 6582144, with 216841-digit probable primes found by Martin Raab. This gap has merit M = 13.1829. The largest known prime gap with identified proven primes as gap ends has length 1113106 and merit 25.90, with 18662-digit primes found by P. Cami, M. Jansen and J. K. Andersen.
code challenge - Find the largest gap between good primes ...
codegolf.stackexchange.com › questions › 65876Dec 07, 2015 · However, when we're looking for "good" primes we can thin the herd even more. If gcd (x, 60) = 1, we find that in most cases gcd (x-1, 60) is either 6 or 10. There are 6 values of x for which it is 2: 17, 23, 29, 47, 53, 59. Therefore we can precompute the "good" primes of the form 2^a 3^b + 1 and 2^a 5^b + 1 and merge them into the result of a ...
