Cheers, Willem.

The results on base 23 are essentially useless...only a small portion from n=187K to 191K. Also, the timings are all over the place, which makes me question the integrity of them. I will double check the range.

Hi Gary,

The timings are all over the place because this is not a dedicated machine going 24x7. This PC is on for 8-10 hours per day and I play games on it. Not much progress when one core is busy slaying monsters.

Cheers, Willem.

Karsten,

You did Riesel base 15 for n<2M in Nov. of 2008. You reported completion of k=1M-2M to n=25K at that time. For k<1M, you only reported completion to n=16.2K on 11/6/2008. Is that all the further that you are going to test it? Shall I unreserve that range?

Does anyone have a working script to do the removal of those ks?

edit: forgot the attachment like usual

After thinking about this for a bit, I've decided not to show these k's remaining or the range as tested on the web pages. It takes quite a lot of time to add a lot of k's to the pages and later on remove them as primes are found for them. In this case, by the time we hit n=10K or 25K for k=2M-3M, over 90% of the k's listed will end up being removed.

For bases with huge conjectures such as bases 3, 7, and 15, in order to show them on the pages, I'm going to have to ask that they be tested to at least n=10K. This would apply only to the portion of the k's being tested. This still allows people to test just a few k's at a time like we've been doing in the past for bases 3, 7, and 15.

I'll keep your listing of k's remaining keeping in mind that appropriate multiples of the base still need to be removed. If anyone reserves the range, I'll forward them the list.

Riesel Base 15 2M-3M is now up to n=25k. I used a script that kar_bon posted to remove multiples of the base. I dont know whether that script has been checked or not.
I will shortly post the files(some are on windows plus i want to use notepad++ on one file). There are 9ks remaining at n=25k.

[henryzz]

after all that i left a file on linux
here are the results for base 15 k=2M-3M up to n=25k
bother they need email
bother back into windows i go(takes at least 5 minutes of waiting to change operating system)

Time to test the last untested base <= 32 that is not b=2^q-1:

Reserving Sierp base 25 to n=25K.

This will take a while. Besides the relatively large conjecture, it will require analyzing many base 5 primes to determine which ones can be converted to base 25. But it should be easier than Riesel base 25, which also required the removal of many k's with algebraic factors that made a full covering set. Afaik, Sierp base 25 has no k's with algebraic factors that make a full covering set.

Ah...excellent! I'll check it and show the k's and primes on the pages with my usual next update.

After some discussion with Gary, I've decided to doublecheck Riesel base 23 for n=180K-200K. This will give us some residuals to put down for our records, and it shouldn't be too hard since I'm guessing my quad can eat it up in a few days.

Karsten,

You can ignore this. I found the appropriate statuses for Riesel base 15 in the "Riesel/Sierp #'s for bases 3/7/15 thread". I've since moved the base 15 statuses/k's remaining/primes to this thread.

Although you didn't specifically state it, it was clear that you intended to unreserve Riesel base 15 for k<1M at n=16180.

To all: Shortly, I'll do another web page update. On the reservations page will be a sieve file that Karsten left for Riesel base 15 for the 14 remaining k's for k<1M and n=16181-100K.

I'll reserve those 14 k's and test them to at least n=25K.
