Bases 6-32 reservations/statuses/primes

[VBCurtis]

5306*28^20994-1 is prime.

[japelprime]

I will probably reserve more of 2036 base 9 number (if no prime will be in my range) but can then slow down on LLR testing to free upp
one older AMD PC to help on Liskovets-Gallot numbers. Maybe not wery fast PC for LLR but will do its job 24/7.
Back to this later.

One for Riesel 31:

69900*31^24581-1 is prime
That leaves 15 k’s
All tested up to 26.2k

Several for Sierpinski 24:

19924*24^13601+1 is prime
19769*24^13627+1 is prime
5631*24^13672+1 is prime
24736*24^13770+1 is prime
27676*24^13986+1 is prime
9476*24^14382+1 is prime
674*24^14541+1 is prime
7291*24^14718+1 is prime
30349*24^14745+1 is prime
6194*24^14989+1 is prime
4196*24^15010+1 is prime
13156*24^15010+1 is prime

That leaves 172 candidates to test.
All tested upto 15k

Is it correct, that Sierpinski base 17, 3 k's are available?
If so: I will take it to n=100k

Sierpinski base 18 still in progress

Yes they are. We'll reserve them all for you.

Be sure and get the sieved file off of the main Sierp conjecture web page. It has all 3 k's in it.

[tcadigan]

my reservation has completed.

attached is the llr output.

I *think* that's all the numbers in the range. I'm unsure because my previous computer crashed and I've had to migrate everything over to a new computer. (hence the reason it took so long as well)

[VBCurtis]

5133*28^7958-1 is prime.

[tnerual]

PFGW Version 1.2.0 for Windows [FFT v23.8]

Primality testing 1291*28^22811+1 [N-1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 3
1291*28^22811+1 is prime! (310.8222s+0.0034s)

Done.

gary, you can update the minimum tested value to 22811 for all the remaining base 28 sierpinski candidates.

[tnerual]

sierp base 28 done up to n=25121 (3 primes allready submitted)

i attach a zip with the LLR results and the sieved file for n=25k to n=50k

i release the k's

[michaf]

Another one down for riesel 31:

30792*31^28604-1 is prime

That leaves another 14 k’s to test.

Thanks for the sieve file, tnerual. I'll add it as a link in the web page.
