[QUOTE=wolfcrey;240738]I realized this merge just now: [FONT=Arial]834372:i1935 = 431424:i1854 = 5208:i10 = 467728[/FONT]
[FONT=Arial]Karsten found it, isn't it?[/FONT]

No, I've only posted the merge-index here.

[FONT=Arial]On my website I set a link to a list of all OE-sequences (there are 9293 now):[/FONT]

[FONT=Arial]I hope this will help you and us all if the information will come back.[/FONT][/QUOTE]Thank you. I'll compare that to my lists and see what I have that's extra....

Wolfgang, your given file and my downloadable list from [url=http://www.rieselprime.de/Others/AliquotIntro.htm]here[/url] contain both the same open sequences.

With thanks to Wolfgang and Karsten, I've got my list double-checked. I found some sequences that I had missed and a few that I had duplicated.

[QUOTE=10metreh;240270]I suspect there are more side-sequences in that list.[/QUOTE]While waiting for the local telco to show, I had a chance to shake the sequence summary a little and see what fell out, and yes, there were several more that I found upon further review.[code]280032:i1600 = 6552:i4 = 78720
493410:i814 = 228522:i1626 = 1785616
773000:i2 = 445464:i848 = 1506320[/code]These were the easy ones to find. They're evident when looking at the list sorted by length; the guiding/driving form on these have the same 4 or 5 small factors....

There may be more hiding in there that could be tracked down with a more automated check. I posted the summary file [URL="ftp://ftp.frontiernet.net/pub/users/aliquot/public_ftp/AllSeq.zip"]here[/URL].

This one I've listed "found by mataje on 2009-07-23" on my Summary pages.
Wolfgang lists this, too, but without date and finder.

I've updated my list with now 9291 OES < n=1000000.

[size="1"]Yeah, kar_bon beat me to finding it....[/size]

With all updates there are now 9291 OE-sequences and 194 cycles with higher order (4 or more). David Moews updated his list, too.

David Moews updated his list, too.[/QUOTE]So that means that if we terminated ~125 sequences in the ~1.5 years we've been really active, we need only 112 more years or so to terminate everything....:grin:
