Okay, [B]k=191[/B] has reached [B]n=400000[/B], continuing to 500000.
I'll also take the following k: [B]151[/B], [B]155[/B], [B]157[/B], [B]161[/B], and [B]163[/B].

There are still quite a few gaps for lower n on Wilfrid Keller's list, especially in the range n=100000-200000 (obviously some of us have never reported their results to him). Therefore I did some double-checking on the following ranges:
[CODE]
k range of n primes
-------------------------------------
23 [120000-151000] --
47 [100000-110000] --
57 [100000-110000] --
59 [100000-110000] --
61 [100000-110000] --
67 [100000-110000] --
175 [100000-133600] --
185 [100000-128100] 109346, 113966
-------------------------------------[/CODE]

I'd like to take k=195. I see it's confirmed checked up to 250k but
a prime was reported around n=311215. (by Shane F.). Should I start
checking at 311216 or back at 250000?

Kosmaj 2006-02-06 22:27

At 250k! Once I asked Shane about the range he checked but he never responded.

BTW, I updated the [URL="http://www.15k.org/riesellist.htm"]stats page[/URL] with all recent reservations and new primes.

Kosmaj 2006-02-08 07:09

I'd like to reserve k=73.

Kosmaj 2006-02-09 04:23

k=195
 
Larry, the latest range completion [URL="http://www.prothsearch.net/rranges2.html"]report[/URL] by Wilfrid Keller lists k=195 completed to 267k (by Sun & Findley). Therefore, you can start at 267k but keep the 250-267k candidates until I check with him (in a few days when I plan to send him my progress report).

For k=25 I have reached n=600000 - one prime found and already reported at n=587585. I'll work on this one some more :smile:

Flatlander 2006-02-09 16:46

125 available? (or 115?)
 
I would like to take 125 from 210,000 unless someone says otherwise.
If someone does say otherwise, then I will take 115 from 210,000 unless someone says otherwise. :smile:

I will also work on my English.

lsoule 2006-02-09 22:19

195 had previously reported primes at n=243999 and n=311215
and I just reported
195*2^272695-1 (82092 digits)

right in the middle.

Kosmaj 2006-02-10 13:55

Flatlander
 
k=125 is reserved for you from 210k.

[URL="http://www.15k.org/riesellist.htm"]Stats page[/URL] updated.

grobie 2006-02-11 15:15

reserving k=139 from 210k

Correction to Post#1
 
On post#1 it says:
When you find a new prime or complete a range please post the info here and also inform Wilfrid Keller so that he can update his lists. His address can be found at the bottom of this page

I just e-mailed Wilfrid Keller with the prime I found, he informed me that what he needs is completed ranges & with how many prime were found in those ranges. So there is no need to e-mail him with individual primes. When you post your prime in the Top-5000 he is notified about those primes automaticaly
