717240: i=1870, size 131, 2^6*127 driver

Sorry, I haven't posted in a while....been getting settled in on a new PC after my previous system threw a fan and (apparently) fried the CPU. Here's my latest:[code]11/20/09
Seq Index Size Co-factor Driver/Guide
29772 1072 125 92 2
170196 1727 136 130 2^3
171018 1844 121 106 2^5 * 3^2
363270 1641 140 126 2^7
604560 2463 129 122 2^6[/code]

I am now done with 112584. Status:

112584; i=1022; sz 117; C115; +56; 2^6*3

There's no driver on this one but I couldn't get rid of the small factors.

I found another sequence < 1M in the database that had a factor of C<70 so I extended it. Status:

730260; i=1088; sz 89; C76; +18; 2^2*7

No reservation.

I found another sequence < 1M in the database that had a factor of C<70 so I extended it. Status:

726672; i=751; sz 103; C101; +1; 2^2*3*7

No reservation.

Here is the current status of my reserved sequences after running them while I was away:

1) 14994 - Index 1769, 120 Digits, 2^2*3, c114
2) 238872 - Index 717, 131` Digits - 2^3*3, c125 - Releasing
3) 511728 - Index 1362, 117 Digits - 2^8*3^2, c100
4) 511734 - Index 613, 110 Digits - 2^3, c97
5) 527436 - Index 1089, 114 Digits - 2^3, c104
6) 527640 - Index 927, 127 Digits - Downdriver, c110
7) 572040 - Index 897, 102 Digits - Downdriver, c98
8) 699000 - Index 667, 106 Digits 2^3*3*5, c86 - Releasing
9) 709420 - Index 963, 115 Digits, 2^4, c92
10) 713160 - Index 1342, 109 Digits, 2^3*5, c90
11) 713214 - Index 1050, 122 Digits, 2^2, c103
12) 721980 - Index 892, 105 Digits, 2^3, c88
13) 724578 - Index 2473, 118 Digits, 2^2*5*7^2, c113 - Releasing

I am releasing 238872. The c125 passed ecm by aliqueit so it has a large gnfs and 2^3*3 is technically a driver, so escape chance isn't good (though better than other drivers)
I am also releasing 699000 as it now has the dread 2^3*3*5 driver.
Finally, I am releasing 724578 which picked up 2^2*7.

527640 picked up the down driver at 128 digits, I will be working on this one to see where it goes.
572040 also got the downdriver at 106. This is the other sequence I will be working on full time.

I will also post the releases in the other release threads.

Two down-drivers at over 120 digits - very nice. Hope they go somewhere for you.

----------------------

572040 managed to get down to just over 3 billion before heading up again. It lost the 2 down driver quickly then as quickly regained it again at 103 digits for a run to 25 digits. Currently has a 2^2 at 86 digits.

Meanwhile 527640 has a c118 to deal with so only got 2 indices further.

The first update from Clifford in nearly a month, and some news:

Paul Zimmermann broke the highest downdriver acquisition record: the record is now 145 digits in 660. He also escaped 2^5 * 3 * 7 at a record height of 146 digits in 552.

Christophe Clavier reports another downdriver, in 4380. This came directly from 2^2 * 7 at 124 digits, a record.

Clifford himself has terminated 98616. It is the first termination below 100000 since September last year, and the second highest termination too.

And of course the record high stability in 4788 :smile:

However, if 4788 gets the downdriver, I wonder how long that record would last! :whistle:

Color me sad

Oh well, at least it only went to 2^2, so you've still got a decent chance of regaining the downdriver.
