16990New Cullen Record
- Aug 25, 2005I am pleased to annouce that I found the largest known Cullen prime
and it comes just a few weeks after my recent Woodall prime record and
seven years after the previous record.
1354828*2^1354828+1 is 407850 digits long
It was found using my MultiSieve program for sieving and Jean Penne's
LLR for the primality test. Once verified it should be #35 in Chris
Of note, I sieved with a version of MultiSieve that I ported to
PowerPC as it can sieve Cullens/Woodalls many times deeper than x86 as
it has many 64-bit registers.
