[quote=Mini-Geek;143565]Yes, it is possible. From the LLR readme file:[/quote]


Has anyone ever actually tried this with LLR? I have in the past and could not get LLR to work with ABC files. It seems to only accept NewPGen and srsieve -g and -G formatted files.

If someone would like to attempt this and can get it to work, please post exactly what you did because I have not been able to.

This works:[code]ABC $a*2^$b$c
599 100001 -1
599 100001 +1[/code]It returns this:[code]599*2^100001-1 has a small factor : 3 !!
599*2^100001+1 is not prime. Proth RES64: 422BF6EDE971AE37 Time : 18.773 sec.[/code]

Do you have the current version? It was added in 3.7.1c (IIRC).

Yep, I have 3.7.1c. I tried what Mini-geek did and it worked! Go figure.

I must have been doing something wrong before...not sure what it was. Thanks.

Sierp base 31 is now complete to n=7.7K. 2242 k's are remaining. See k's remaining and highest primes on the web pages.

Continuing on to n=10K.

As Micha has found on the Riesel side, this is a very prime base. The k's remaining are very few for such a large conjecture (k=6360528) and high base.

BTW: [I]srfile /w[/I] (PFGW) generates such an output: [code]ABC $a*10^$b+$c // Sieved to 1000000000 with srsieve
4421 195028 -1
7666 195161 1[/code] and it works under LLR :tu:

Status report: Base 31, riesel now at 94k.

Did you find any primes on base 6 lately? A prime there can also knock out a prime for base 36 after all.

Willem.

no, not yet.
k=1597 is at n=167k
k=9577 is at n=110k
the other 11 k's at n=99k.
testing further!

base 9 Sierpinski. k=2036. I am in n= 270k no prime.

Gary I have sent you the results 260k-270k some days ago.

Riesel Base 6
 
after a long dry search for this base:

21799*6^99609-1 is prime!
