Good luck!

i thought i was
did u test all the way from 1 to 300k as i found several low primes that were not on rieselprime.org

I take k=1963, at least to n=500k.

Already completed up to n=120k. (My first small contribution here

)

Primes for n=

7, 11, 15, 55, 91, 95, 127, 131, 135, 847, 2379, 2471, 8831, 11527, 11967, 17439, 26619, 26899, 28519, 36635, 36695, 81975

All confirmed from Rieselprime, except n=81975, which is new (previous search up to n=50k).

1009 and 19920911 are now at 350k with no new primes
i stopped a while to sieve both to 1T at 300k

mcduck · 2008-10-13, 17:00

I'v tested K=777777 to n=100k (mostly to learn hos to use the different sieving programs out there)

Primes;

1 2 5 10 18 29 36 44 45 49 54 68 82 101 134 140 146 154 180 213 230 249 326 445 480 540 592 729 817 890 1010 1454 1506 1806 1928 2438 2726 3294 3806 4049 4146 4309 4732 4746 4770 5536 6153 6161 6618 6997 8081 9242 9660 10860 13526 19584 25820 28156 29944 30474 32553 95424

I am planning on testing this K to n=300k

henryzz · 2008-10-20, 18:41

1009 and 19920911 are now at 400k with no new primes
i am going to stop at 500k

Templus · 2008-10-21, 10:29

As I have been unactive for this year with reporting I now officially unregister my following k's as on the Riesel List :

- 11069
- 11411
- 20639
- 21869
- 10453199
- 10813783

However I will keep on testing the following k:

- 25935

19920911*2^425326-1 is prime

my second top5000 prime

henryzz · 2008-10-30, 18:13

i started testing 1145699 a few days ago
i am now at 543k with these primes
1145699 108
1145699 372
1145699 1068

AES · 2008-11-02, 04:06

Congrats on the k=19920911 prime. And good luck with k=1145699.

k=19920911 is a low weight k so i was rather lucky
k=1145699 only has about 700 tests from 1 until 1mil so that is an especially low weight k
what i am doing with k=1145699 is easier that a 6th drive file i think

Nomarcland · 2008-11-02, 10:57

k=1963 tested up to 220k and moving on.

One new small one, n=169071.

k=7605 tested from 439k to 452k and moving on.

Nothing found.
