k = 13854 is at n = 261944 base 2 (so, 128K base 4).

I did'nt worked yet on k = 16734.

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.

Default no prime in range

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)

Done.

Another one down for riesel 31:

30792*31^28604-1 is prime

That leaves another 14 k’s to test.
