So that answers Bob's question. I wonder why he thought the factorization was missing? Something else may be wrong.

[/QUOTE]

The result was not among any of the updates that you published,
nor was it entered into the actual 6,5- table.

Paul[/QUOTE]

Paul, I think the problem is that this update is missing a bunch of factors that have been found since the previous update. You reported 17 factors, but there were 409 composites as of the previous update, and 383 after this one. So there must have been at least 26 factors.

It appears that this update only goes back to 2013-10-23, and the previous one only goes as far as 2013-09-28. As your update file shows, the factor Bob flagged (as well as apparently 10 others) were reported in the intervening time.

Mea culpa. I update these tables erratically and largely by hand --- only the arithmetic is performed for me. Clearly, I need to develop a more systematic approach.

The GCW tables, OTOH, all live in a PostgreSQL database and some heavy Perl scripting does at least 90% of the work. The results are much more reliable, though not perfect, as Sean Wellman mailed earlier today. The reservations and Most Wanted Numbers lists are maintained entirely by hand. Sean noted that a reservation has already been completed. As a GNFS will finish tomorrow I'll roll both updates into the same session.

I've been thinking about putting the Homogeneous Cunninghams into the database for quite a while now. As always, round tuits have been in short supply.

I'm on a current crusade to fill in first holes.

[QUOTE=R.D. Silverman;360883]Do we know which numbers were missed?

I'm on a current crusade to fill in first holes.[/QUOTE]The tables on the web are current and complete as far as I know. No new factors have been reported to me since 27th November, the date of the last upload.

This gives the first hole in each table right now.

[QUOTE=R.D. Silverman;360883]Do we know which numbers were missed?

I'm on a current crusade to fill in first holes.[/QUOTE]

Nothing is missing in Paul's tables (with one exception, below). All that went wrong was Paul's report in this forum of 2013-11-27 ([url]http://mersenneforum.org/showpost.php?p=360421&postcount=1115[/url]). Instead of only the 17 factors shown there should have been an additional 11 factors. The UPDATE file on Paul's web site contains them; you just need to go back to 2013-09-29 instead of only as far back as 2013-10-23.

The exception I mentioned above is 11+5,238, which is no longer in the reservation page, but has not been reported by Paul. I assume that whoever factored it did not report it to him. It does appear in the factordb ([url]http://factordb.com/index.php?query=11%5E238%2B5%5E238[/url]), and was apparently added on 2013-10-12. Perhaps Tom can tell us who did that one.

11+5.238 is in my database as being done by Ben Meekins at 2013/10/13 20:09:45 having been reserved at 2013/09/29 20:56:31

Yes, I did that number. I posted the factorization in this thread (here: [url]http://www.mersenneforum.org/showpost.php?p=356077&postcount=1114[/url]), and I thought I had reported it correctly, but it is entirely possible that I forgot and/or didn't do it properly.

Ah indeed. I must have scrolled past it numerous times and never noticed. In any case, the only "correct" way to report the factors is to email them to Paul. He makes no guarantee that he will pick them up from postings here.

As noted, emailing is by far the most reliable way of getting your work noticed. Otherwise it will most probably get picked up sooner or later but may well take time and cause a modicum of confusion in the interim.

Added in edit: the method of factoring wasn't stated. I'm guessing GNFS as the composite is relatively small.

It was actually SNFS--as I recall the SNFS difficulty was slightly less than the GNFS difficulty.

Edit: Just found the poly file and confirmed that it was SNFS.
