Speaking of large gaps between primes - There is a Bitcoin clone recently released called "Gapcoin" which replaces the SHA256 hash-breaking with finding large prime gaps. It seems completely unknown and has very few people mining it, yet it already broke a few hundred records, and is one spot away from breaking Donald Knuth's record in the "top 20 highest merit gaps"<p><a href="http://primerecords.dk/primegaps/gaps20.htm" rel="nofollow">http://primerecords.dk/primegaps/gaps20.htm</a><p><a href="http://gapcoin.org/primegaps.php" rel="nofollow">http://gapcoin.org/primegaps.php</a><p>I am curious if there is any scientific use for finding these high-merit gaps? Or is it the same usefulness as finding a slightly longer expansion of PI?
