Question Shall we fill in some holes?

Actually, it's going to take a while to "run out" of good sequences. I'll just have to put some time into the required research to keep ahead of the wave on those.

As far as the 200k range goes, there is some work to be done there. Sander is working on the sequences in the 200-210k range and Wieb Bosma is working on the range from 250-350k, so we can rule those out.

However, there is the range from 210-250k where Wolfgang was in the process of extending everything from 80 to 100 digits. The only problem is that we don't have most of the files for the 80 digit work; which actually is not that big a deal, because even on this ancient machine, I can run a sequence from start to 80+ in less than a couple of hours....

If there is interest in some "easy" work (antiroach?), we could start a thread dedicated to filling in the holes in the 200k range, where the goal is to run a bunch of sequences from start to 100 digits. There is a small chance of finding a terminating sequence (could be through termination, hitting a cycle, or joining another sequence), but, as in life, there are no guarantees....

Hmmm. I see you've got some .alq files on your site from that range. Are any of those ones stable?

I haven't cross-checked this list against the files that Clifford sent, so I don't know if we have all the sequences listed or if there are sequences listed that we don't have, but here is the "rest" info on the files that Wolfgang had referenced on his site.....

This is sorted on the guide column, and as soon as I cross-check it with the files I received, I will post it on my site.

The 200k range is very much more disorganized than the 100k range, since it was in the works last year.

Meanwhile, I was wondering whether you could mark reserved sequences in your 100000-200000 "rest" file with "R" or "resv" or something like that.

Go ahead and take numbers from this range. At the moment I'm slowly bringing all sequences to at least 110 digits. My site is up to date except for the following sequences which I'm running at the moment.

201978
202656
202788
206694
207102
207822

BTW Paul Zimmermann is working on 204828. You've got it listed as 118 digits on your site.

Thanks, hadn't spotted he had only put the file up to 4117 there.

I'd be interested in doing some of this 'easy' work. Just let me know which sequences to work on and where to get the .alq files and i'll gladly contribute.

I forgot to mention that I'll be glad to do some work on this (a stable sequence at 80 digits would be excellent! )
