Please check your k's remaining list for group 14. There are 7538 primes and 7538 k's remaining.

If I screwed that up, don't worry about it. I'm tracking all submitted primes and will provide a consolidated file of primes and remaining k (ensuring no duplicates and no missing k) when completed, which could be as soon as Monday this coming week. Some of the submitted files have multiple primes for some k, so I've had to fix those locally.

"If" the list is wrong?? Like I said, you have the same number of primes as k's remaining?! There could be no "if" about it.

If you want to wait until the end, I suppose that is fine. I was just hoping to do them in smaller pieces. At this point, it's not easy for me to piece-meal out exactly which k's are remaining for each group (if the list is not posted or is incorrect) since the group links in the 1st post were dead long ago so I removed them. That means I no longer have the easy lists of 10,000 k's to start from for each group. I can go back and determine each group's k's from the original 237,036 k's remaining at n=1K but that would take a little while.

If interested, PM me and I can send you the code changes or a Windows exe. I'll send my changes to Geoff. Hopefully he will incorporate them in his next release.

I don't think this feature has been incorporated, has it? Neither readme nor -h say anything about it. I am interested in this .exe, because I had to do this using a batch file that wrote the remaining candidates after each sequence removed which wasted a lot of time on R301. For future high conjectured bases this will be very useful.

Thanks

Puzzle-Peter,

Your srfile needs to be upgraded. If you go to Geoff's page

Download srsieve-0.6.17 latest binaries, it will contain srfile and has the implementation for -d. This version will also show this option when using the -h command.

It only says it can remove a single sequence. What rogue mentioned was reading sequences from a file and remove them all. I don't see this when using -h. Am I mistaken? These files (v0.6.17) seem to date from 2009 whereas rogue's post is more recent.

You need to use srfile, which is included in the d/l for srsieve.

srfile 0.6.17's -h is:

srfile 0.6.17 -- A file utility for srsieve.
Usage: srfile [OPTION ...] <INFILE ...>
 -o --output FILE         Write sieve to FILE instead of srsieve.out.
 -k --known-factors FILE  Remove factors in FILE from the sieve.
 -d --delete SEQ          Delete sequence SEQ from the sieve e.g. -d "254*5^n-1"
 -g --newpgen             Write sieve to NewPGen format files t*_b*_k*.npg.
 -G --prp                 Write sieve to PRP (sorted by n) files t*_b*.prp.
 -w --pfgw                Write sieve to pfgw (sorted by n) file sr_b.pfgw.
 -a --abcd                Write sieve to abcd format file sr_b.abcd.
 -Q --subseqs X           Print base b^Q subsequence stats for all Q dividing X.
 -c --congruence X        Print congruence (mod X) information for sequences.
 -p --pfactor X           Print Prime95 worktodo.ini entries for P-1 factoring.
                          X is number of PRP tests saved by finding a factor.
 -v --verbose             Be verbose.
 -q --quiet               Be quiet.
 -h --help                Print this help.
 INFILE ...               Read sieve from INFILE.

No mention of files, but the feature is there!

C:\...>srfile -d seq.txt srsieve.out
srfile 0.6.17 -- A file utility for srsieve.
Read 4071903 terms for 4999 sequences from srsieve format file `srsieve.out'.
Sequence 2^n+1 was not found
Deleted 1025 terms for sequence 2^n+3.
Deleted 724 terms for sequence 2^n+9999.
Removed 2 sequences with from `seq.txt'.
Wrote 4070154 terms for 4997 sequences to srsieve format file `srsieve.out'.

(where seq.txt contains lines like "2^n+1")
And it supports files of primes:

C:\...>srfile -d pfgw.log srsieve.out
srfile 0.6.17 -- A file utility for srsieve.
Read 4070154 terms for 4997 sequences from srsieve format file `srsieve.out'.
Deleted 811 terms for sequence 2^n+7867.
Deleted 776 terms for sequence 2^n+4795.
Deleted 1071 terms for sequence 2^n+897.
Deleted 474 terms for sequence 2^n+3767.
Deleted 849 terms for sequence 2^n+7167.
Removed 5 sequences with from `pfgw.log'.
Wrote 4066173 terms for 4992 sequences to srsieve format file `srsieve.out'.

(where pfgw.log contains lines like "1*2^18542+7867")

It was added in a (relatively) recent version, so if you're having trouble besides the lack of mention in help files, update to 0.6.17, which is included with srsieve.

Aaahhhh, so that's what confused me. Thank you folks!

Group 17 done as is this sub-project. 7673 primes.

I will place a zipped file with all primes and remaining k into the base 33-100 thread.
