New reservations:

59232
244140
250824
305454
392430
472500
473502
646296
750372
763476
842592
892440

From my perspective, this is an exciting effort. Some (but not all) of these are the highest index sequences with some of the lowest remaining factors as shown on [URL="http://factorization.ath.cx/search.php?so=1&se=1&2=1&1=1&5=1&3=1&start=2&limit=100&len=1"]this page[/URL] in the D.B. The listing can be obtained by going to "sequence overview" in the D.B. and clicking on "length". Nothing else needs to be done.

392430 has already been extended over 630 indexes from where I started to i=~5380, which has moved it from 24th to 13th place on the listing. 842592 has already been extended over 2000 indexes from where I started to i=~6180, which has moved it from 55th to 7th place on the listing!

842592 is definitely the wildest sequence that I have personally encountered.

...picking off more "low hanging fruit". There's plenty to go around. Let's use the above listing and see if we can get our first 10000-index sequence! :smile:

A couple of quirks about the listing:
1. It does not show sequences > 100M. This is apparent if you change "start" to 9999999 and then click on length. It only has 22 sequences listed with a length longer than 1 (that is sequences 10M-100M), which is clearly incorrect since I've done many larger ones (namely powers of 10) to 70 or 80 digits when I was playing around with the sequences a while back.
2. The length is only "counted" until it merges with another or lower sequence. This makes sense because otherwise, in effect, multiple sequences would be counted as one.

Gary, 244140 is reserved by me.

OK, sorry. I missed that. It's yours. I extended it 1 index before catching your note here. lol :rolleyes:

Out of curiosity, I just ran the .elf file as created by the DB for sequences 517392 and 518568 through aliqueit.exe to see what the errors were. I found that there were no errors. Am I missing something?

Currently, I think one can fix any sequence with errors, so there shouldn't be any errors anymore. The 'repair sequence' allows you to fix.

Yeah, I figured that but thought I'd point it out to the admins here so that they remove it from the 1st post here.

There is a strange quirk that I've observed with the repair. If your sequence merges with other sequence(s), you have to repair the lowest sequence that it merges with. It won't let you repair your higher sequence. This was very consistent across multiple squared-line bugs that I encountered when doing very large sequences (i.e. > 10^20). I was able to repair them all but had to choose the lowest sequence in which they merged with to do so.

Previously I thought there was a bug in the "repair sequence" link. lol
