2 more primes (too small for prime pages)

Code:

13236795*2^1066721-1
13236795*2^1067293-1

ValerieVonck · 2017-01-29, 14:09

2 more primes found: (too small for primepages)

Code:

13236795*2^1176214-1 is prime! (354083 decimal digits)
13236795*2^1196191-1 is prime! (360097 decimal digits)

ValerieVonck · 2017-12-16, 10:14

Range 1.2M -> 1.3M complete, no new primes found
Attaching the result files for the range 1.0M -> 1.3M

ValerieVonck · 2018-02-19, 17:24

Sieving in progress, till 230T, ETA 20/3
Will then continue llr testing in the range 1.3M -> 1.4M

ValerieVonck · 2018-05-26, 08:29

Sieving in Progress to 250T, eta 03/07
(ftm, a factor is found every +/- 360 sec)

ValerieVonck · 2018-06-04, 14:47

Yesterday, my mac crashed and had to restart sieving from a copy of my input file as of February,

Currently at 216T, eta for reaching 250T is October

Lesson learned: take a more frequent backup

Apologies to the community
Kind regards,
Valerie

Why you make sieving ? We can collect you sieve , send to YOYO and it will be over in ten days at depth you will never reach by yourself.

Dear,

This number I am crunching for a long time on my own...
Thank you for your recommendation, but I have to politely decline your offer

Kind regards,
Valerie

Sieving to 250T is completed, sieving in progress in the range 250T -> 255T,
Finding a factor each 300-400 sec, still faster then LLR,

Kind regards,
Valerie

I find it really inspiring how long you've been working on this k. I started sieving for Proth k=1281979 some months back, now I'm at around 250T as well, but only for n < 4.1M. So 2 cores produce a factor aprroximately every 2000 s between them. Primality testing will be done using Proth20 on an older GTX7xx GPU, which takes 3.5 h for a = 4M so I'll continue sieving for a while.

If I will do this with the same dilligence as you, I'll still be at this k it in 2035... :)
