What? The prime that you just submitted a couple of hours ago doesn't look familiar to you? lol
In the mean time, can anyone say 12 in a row new primes for k=16001700?:
1689*2^3623881 is prime
If this continues for another couple of primes, I'm going to do some serious investigation on # of k/n pairs/avg. weight/what k's have already been searched/etc. I may have been in primesearching for only 21 months, but this is not something that should happen once in 21 months...more like once in 21 years!
I'm quite confident that k=18001900 & 19002000 have been searched no more than k=16001700 so if you allow the 1st prime in the streak to be any one of the 3, then the chances on any 12prime sequence coming up 12 in a row in one of the 3 are 1 in 3^11 = 177147.
What that means is that I would have had to have witnessed or been involved in the searching of 177147 top5000 primes by now. In 21 years, sure, but not 21 months. In nontop5000 primes, sure, but not top5000 primes.
Go figure!
