kar_bon:
After asking L.Soule (he tested the range n=200k to 857k or higher), he is not aware of the top range he tested and got no old results from this k-value.
The last prime found was at n=857k.
So I set the testrange of this k up to n=857k for now.
Summary-page updated.

Hello
 
Hello, I'm back. I would like an update on my reservations, so I can tell you guys how far I've gotten.

Thanks.

I'd like to reserve k=45045 [SIZE="1"](I'll start testing it from n=50k on using only a few cores)[/SIZE]

unconnected 2013-09-19 13:40

Hello! I want to reserve these k's if they are free. Also please confirm test limits.
Low-weight:
8887 10K
5951 10K
5293 20K
7807 50K
5339 20K
And one high-weight k=3645 from n=1M.

[QUOTE=unconnected;353440]Hello! I want to reserve these k's if they are free. Also please confirm test limits.[/QUOTE]

I've reserved all those k-values and the test ranges are correct.

Good luck.

[QUOTE=henryzz;355921]Unreserving 2041, 56627[/QUOTE]

Any results or ranges done from these k-values?

henryzz 2013-10-11 17:56

[QUOTE=kar_bon;355929]Any results or ranges done from these k-values?[/QUOTE]
None since last report. I had forgotten I had them.

rajula 2014-06-30 12:13

I would like to reserve the low-weight k=9913 for testing.

Also, it will soon be one year since the reservation for k=45045, so I thought I should give an update on it. k=45045 is now tested for n from 50k to 1190k and the primes found on that range are with n=
52475
53187
54531
61667
94851
118236
192100
203302
217560
282918
579153
713900
904637
956063
1101198
1132151
(only 1101198 is on the top-5000 list, others were found after the cut-off)

I am still continuing (at least for a while) also with this k.

[/QUOTE]
I've tested this k to n=3M.

rajula 2014-06-30 12:36

[QUOTE=unconnected;377054]I've tested this k to n=3M.[/QUOTE]

Thanks for the info (I did not find a reservation or status-update for the k with a quick search). I was planning on putting one core to crunch one low-weight, already sieved, low-n k, but perhaps I'll dedicate also that core on running ECM (stage 1) on F12.

[B]I unreserve the k=9913[/B] then and continue slowly just with 45045. (Maybe [url]http://www.rieselprime.de/[/url] could be updated on k=9913).

edit: on a second thought: [B]I could reserve k=3907[/B] (if it is not also tested to the 3M heights.. It is not complete obvious for me where I should check the reservations)

pinhodecarlos 2014-06-30 14:05

k=3907 is reserved by Free-DC Prime Search but it has been a dead project for the last year.

Did you mentioned this effort in this Forum? If so, please give me a link, so I can insert it on my page. Thanks.

[QUOTE=pinhodecarlos;377059]k=3907 is reserved by Free-DC Prime Search but it has been a dead project for the last year.[/quote]
It's not reserved on my pages because FDC is dead for a long time, only primes found by Burt were inserted.

Batalov pointed out by pm that these ks are even. Not sure how this has been missed for this long.

LaurV 2016-09-05 05:37

Can they come from some 4^n or higher "crus"? As it seems most of the n's are also even, and most of the k's are 2 mod 4?

[QUOTE=LaurV;441600]Can they come from some 4^n or higher "crus"? As it seems most of the n's are also even, and most of the k's are 2 mod 4?[/QUOTE]

I am pretty certain none match up. The numbers in CRUS have been tested higher anyway.
