k=13236795

ValerieVonck · 2006-10-30, 10:37

Dears,

This dates from the 15K search
Can anyone verify that this K isn't assigned to anyone?

If not, can I test if further?

Thnx

From what I've managed to find you have tested this "k" till n=360000, I don't see anyone else working on it since then

BTW: there are no reportable primes for this "k"... yet

ValerieVonck · 2006-10-30, 14:17

ok then I reserve it! I almost sieved it to 1T

to 425K

Primes found

Code:

13236795*2^167188 - 1 is prime!    50336 digits
13236795*2^199020 - 1 is prime!    59919 digits
13236795*2^199516 - 1 is prime!    60068 digits <= Reported
13236795*2^215582 - 1 is prime!    64904 digits <= Reported

Maybe it would be a good idea to merge former 15k reservations / status reporting with RPS' "Choose your own k..."?

VBCurtis · 2006-10-31, 03:19

I'm still sporadically working on getting the 15k stats page aligned with the "choose your own k" thread and the "report small primes here" threads. Once that project is done, I'll consider going back to the 15k threads/reservations; however, since that subforum is dead, we have to assume anyone who has a reservation that is no longer active on the forum is also no longer searching.

In other words, anyone who wants to work on a 15k reserved from the old days risks duplicating work that an inactive poster has already done.

Among old 15k members it seems that only L58 (Henrik) is still working on his Ks, this year he reported primes for k=587650635 and k=978847155. SlashDude told me that he stopped all his clients. I stopped k=3611911875 at n=400k and k=115029915 at 385k (with gaps done to 403k). I'm still working on k=445419975 (now at 401k).

I still have k=869688105 nominally reserved, although it is quite some time since I last worked on it. As I have taken it to n=570k it is probably unlikely that I will work on it again as it is a high weight k.

Well, I am still working on k=736320585, which is heavy (~145 candidates per every range of n=1000 after sieving till p>10^13). So far I have reached n=500000

ValerieVonck · 2006-11-26, 19:06

FTM, I am 363514 for k, still no primes to report.
Sieved to 885G, (from 363K to 430K), P-1 in progress, elimanting 60+ tests already.

BTW, is this normal (a gap of 150K)?

RegardsC.

Well, for k=736320585 I've had a gap of ~140k, so be patient

ValerieVonck · 2007-01-23, 21:57

Still holding strong @ 371496, P-1 continues, sieved to 930G,
I am getting speeds of 1430+ kp/sec with sr2sieve instead of 430 kp/sec with prothsieve sse2.
