[QUOTE=Dubslow;449250]Going away for three weeks with no remote access. Here's hoping it doesn't die while I'm away. This is quite likely too much work for the time needed, but I'll likely just unreserve it all anyways when I get back.

I was carefully watching the factordb and it was not being processed by the workers. The composite size when it was first poached was over C100 and the database had hundreds of unprocessed C80's and 90's. Anyway whoever was doing it stopped after adding about 400 iterations so I am working on it again.

Dubslow 2017-05-04 06:18

As has been noted in the other thread, P Zimmerman has unreserved 276, the lowest unterminated sequence, due to a C201 surviving a t60 of ECM with no luck. Do we the forum want to take this on? It should be mostly doable as a team effort, with the notable exception of linear algebra requiring quite substantial centralized hardware. We'd need a pretty solid commitment from certain individual people to reserve 276 in good faith.

Given its relative importance to this particular subforum though, I would be happy to dedicate my (extremely limited) resources to it.

Oh, and yoyo/ChristianB, it seems to me that the suitable course of action would be to remove PZimmerman's reservation of 276 from the site. And incidentally, what's the collective opinion of all contributors about perhaps examining and removing certain other "ghost" reservations from people who don't seem to have made progress in many years?

[QUOTE=LaurV;458263]Do you mean like 98904, 964680, and 125016? :evil:[/QUOTE]

Well I assumed my intent was clear :smile:

To be accurate, removing certain other ghost reservations where 1) the reservation itself is years old 2) the sequence hasn't been updated publicly/on the FDB in years, and 3) the reserver in question hasn't made contacted in years and is unable to be contacted before the reservation is dropped.

And to unhijack the other thread (perhaps a mod could assist in that endeavor?)...

[QUOTE=swellman;458302][url=http://www.mersenneforum.org/showthread.php?t=11615&page=256]Ryan took back 4788 in late March[/url], though progress has slowed since.

I'm willing to help with AS276, though yoyo would be the logical player for ECM. Can this effort fit into the 15e siever? It's a daunting task![/QUOTE]

I suppose when I said "we" for 4788 I rather did mean "Ryan" :smile: and of course I meant him in certain other tangential references as well. We'd probably need to hear from him before committing to a C201. Glad to see there's some interest to it though.

[QUOTE=vasyannyasha;458851]Can i take 974610?

It's not in the list. Probably because a smaller sequence merges with it (even smaller than [URL="http://factordb.com/sequences.php?se=1&aq=974610&action=range&fr=25&to=33"]114800[/URL]). I couldn't find in the forum here so it must be a really old merge.

My DB shows a merge to 102936 -> 114800 -> .... -> 974610 in the very early stage (i.e. known many years ago).

Well, now you (LaurV) have it. The script does not check if the keyword is before or after an eligible number. But this can easily be solved by dropping it again and vasyannyasha just needs to reserve it.

You can see the details on this page :

Aliquot sequence 19560 stopped at index 590 with c203 (tested up to 60 digits by ECM).

Up to now, at each iteration, each term of this aliquot sequence increases by a factor greater than or equal to 2 compared to the previous term.
