Riesel Primes k*2^n-1, k<300 [Was "k=1"] - Page 43

I´ll take a look at k=101 from n=500000

Kosmaj · 2006-07-29, 14:02

Sounds good! k=101 is an intersting case, 9 primes for n<10k, one at 94k, and then none to 500k

I hope you find the next one soon

Also I will investigate k=137 from n=966000

VBCurtis · 2006-08-09, 20:05

Update:
k ... n-value
99 .... 400k
127 .. 700k (double-checking, due to errors on first run to 850k)
103 .. 445k
201 .. 275k

k=101 tested till n=600000.
I'm still working on it

Going to take k=83 a bit further

Templus released k=199.

He found one prime at n=263051 but he lost record of what exponents he checked and is suggesting that the next person restarts tests at n=250k.

Status Update on k=83

Tested to 450k (No Primes)

Continuing Further...

Reserving k=181 from 600k onwards

Kosmaj · 2006-08-25, 22:09

Larry, that's a good idea, to work further on k=181 which produced so many primes in the 2nd Drive. It will be nice if you can sieve it for example to 2M and at some point, when you get tired, donate the rest of the file to RPS.
