Default 119098*5^193933-1 is prime!

This one had a high weight: 1027 - so this find should remove a large number of tests from the dat file.

Default 167246*5^195250-1 is prime

a new one ...

i was doing the +1 since a while, i just switched 3 core to -1 one week ago and yeah a fabulous gift: a new prime:

167246*5^195250-1 is prime (around top 1250 in primelist)

it's a medium weight k (535) so it will remove around 20000 k/n pair from the sr5data file

let's go for a new one !

time to test : 5601.166 sec on a centrino-duo 1600Mhz

LLR tests only k*2^n1 numbers, so, we will do a PRP test of 31738*5^196001-1
31738*5^196001-1 is a probable prime. Time: 4892.427 sec.
Please credit George Woltman's PRP for this result!

Default 213056*5^195968-1

213056*5^195968-1 is prime!

birdman2584 must be on vacation - one of his machines found this prime on Monday and he hasn't posted it on the forum or responded to pm/email.

213056 is a fairly high weight sequence, so this find will shrink the dat file some and remove many candidates from the testing queue.

Looking at the stas we can see that we have reached a new small milestone with this latest finding.

We are now below 3 Million untested values in the riesel queue.

After a long drought on the Sierpinski side,
...rover found that

5114*5^268127+1 is prime!

This was a nice find, as rover was slowly, but steadily, attacking the Sierpinski queue.

The prover code doesn't credit the project or srsieve
