Here are the k's that I have left over for Riesel 25. They are all checked until n = 10,000. I will bring them all to 25,000

I’ve checked upto 25k now

Micha,

Can you send me a list of your k's remaining?

There's a little confusion on the count remaining here. I previously showed you with 197 k's remaining at n=17.3K. You showed 34 primes here but are now saying that there are 170 k's remaining at n=25K, which is 7 different than 197 - 34 = 163.

In the mean time, I went ahead and showed it with 170 k's remaining on the web pages.

Perhaps the difference has to do with algebraic-factor k's remaining that need to be removed or k's that are a multiple of the base that need to be removed that have k divided by the base still remaining without a prime. I may have been aware of some of those values previously but am not at the moment.


Thanks,
Gary

Willem,

You are listing primes as high as n=18K. Are all k's checked that high or just some of them?

For now, I'll assume some have not been tested above n=10K and will show that on the web pages. Let me know if otherwise.

Some of them. I was bored to list which ones as it is my plan to take them all to the same 25,000

Sierp base 16 k=2908, 6663, and 10183 are now complete to n=200K. No primes.

I'm now unreserving these.

[Siemelink]

Hiho everyone,

I realized yesterday that 25 = 5^2 and that I can use the primes from the base 5 search. So I've gone through all the posts on the Riesel 5 forum. I found 97 primes from the Riesel 5 search that overlap. And there are 69 k's that show up for both conjectures where no prime has been found yet.

I've attached the remaining k's.

And the primes.
