I am now done with 216840. Status:

216840; i=4733; sz 103; C101; +34; 2*3

All sequences < 100M in the DB that are i>4250 are now at C>=100. This warms my heart. :-)

[quote=biwema;195198]Sequence 859974
Finally passed index 6000
After 49 indexes at 119 digits it got the downdriver an could reduce to 112 (it is not much but better than nothing), then first with 2^4; later with 2^2 moving around 112-113 digits.

Now continuing at index 6013: 112 digits, c109[/quote]

You might consider entering everything in the database now. Per the list [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"]here[/URL], your sequence would be the 12th longest at i=6013.

You can run aliqueit -s 0 <seq-num> in the directory without stopping the run. I do this every few days so I don't lose as much if something happened to the computer. You need wget though.

[QUOTE=gd_barnes;195249]Yep, I set that one a few weeks ago. It escaped 2^6*127 at 108 digits and went almost immediately to the much more dastardly 2^5*3*7 before I finally gave it up at 110 digits. You just can't win on some of these sequences.

Is there a table somewhere of record height escape from most of the common drivers?[/QUOTE]

The highest I know of are:

2 * 3: 139 digits in 1464
2^2 * 7: 126 digits in 1464
2^3 * 3: 156 digits in 1074
2^3 * 3 * 5: 135 digits in 167148
2^4 * 31: 130 digits in 102000
2^5 * 3 * 7: 150 digits in 1134
2^6 * 127: 108 digits in 473502
2^9 * 3 * 11 * 31: 133 digits in 363270

Please inform me if a) you break any of these or b) you find an escape that is higher than one of these.

I am now done with 425052. Status:

425052; i=1008; sz 106; C102; +176; 2^2*3*5

[URL="http://factorization.ath.cx/search.php?se=1&aq=14994&action=last20&fr=&to="]14994[/URL] hit a down driver at 112 digits. Has gotten back to 106 digits so far.

I am now done with 100644. Status:

100644; i=365; sz 113; C102; +4; 2^3*3*5^3

I checked the database for sequences < 1M remaining that still had factors that were C<70. I found 7 of them and advanced them to C>70. Here are their statuses:

247560; i=791; sz 100; C82; +2; 2*3
303072; i=293; sz 86; C71; +12; 2^3*3*5
443460; i=778; sz 85; C78; +15; 2^2*3*5*7
455460; i=463; sz 88; C84; +3; 2^3*3*5
971676; i=1228; sz 98; C75; +14; 2^2*7
971946; i=1126; sz 91; C75; +3; 2^2*5*7
973380; i=1338; sz 96; C90; +2; 2^2*7


No reservations here. All sequences < 1M are now at C>=70.

...filling in more holes. :smile:

I was wondering why C70 was the smallest cofactor. Seemed unlikely to be by chance.

I assume you use the sequence overview to find them?

That is correct.

At some point, I may advance some of the numerous C70's to C>70. By my definition of "advance", it means I have to advance a sequence until it has a "hard" factor of C>70 with "hard" defined as surviving 3 "quick ECM's" in the D.B. as well as the standard number of ECM curves in aliquet.exe. Many times, I'll add 20-30 or more indexes before I consider it fully advanced past C>70.
