10metreh: moved to Status Updates thread

It only held the downdriver for 13 indexes before losing it to 2^3. It then kept various powers of 2 but no other small factor for 61 indexes before aquiring the 2^2*7 driver. It maintained that for 21 indexes before going to 2^2*7^2 followed by aquiring the downdriver again, once again at 100 digits! I've now held the downdriver for 7 indexes with quite a few indexes with factors of 7 but no "regular" drivers.

Although not as wild as 842592, 250824 has certainly been entertaining and I've now added 338 indexes to it and am at i=4249.

You're right.....sorry, I had the stable/unstable colors mis-remembered. How's this? (As of 9/28/09:)

  Seq   Index  Size  Co-factor   Driver/Guide
 29772   1017   134    128       2^2

Ouch....I think I sprained a finger! Does the forum have a medical plan?

extended 564396 from index 623 with a 2^6, get a downdriver at i=652 and it's now again at 103 digits at i=1228

I am now done with 59232. Status:

59232; i=5442; sz 111; C109; +19; 2^4*31

A mystery worker searched this one over 100 indexes not long after I reserved it so I only extended it 19 more.

It is currently 17th longest by length for sequences < 100M in the DB.

I'm releasing this. It's got a promising guide, but just picked up the 3 and will start climbing, so I think I'll let someone else take it for a spin. So that I don't have to move it back and forth, I won't move it from the reservations to the released thread. (unless nobody takes this within a couple days)

2^2 * 3 is the easiest 3 to lose IMHO

I am now done with 250824. Status:

250824; i=6142; sz 105; C100; +2231; 2*3^2

After advancing this one over 2200 indexes, it is now the 9th longest sequence < 100M in the DB. I'm also just about done with the 8th longest.

I am now done with 283752. Status:

283752; i=6430; sz 108; C101; +1662; 2^6*3*5

I am showing this as 2^6*3*5 since that is what it was for 4 indexes up until the very last one where it went to 2^7*3*5.

This is the one in the "a little request" thread. Having advanced it 1660+ indexes to 17 past where Bosma presumably had searched it at i=6413, it is now the 8th longest sequence < 100M in the DB.

This is fun. I've now recently advanced 3 sequences all 1600+ indexes to put them at 7th, 8th, and 9th longest. The 7th place one, 842592, was subsequently picked up by someone else and is now in 6th place at i=6543.

BTW, 250824 and 283752 at 105 and 108 digits respectively have still been searched to a much lower size than the top 7 longest. The top 7 have all been searched to > 120 digits. So someone may be interested in extending these two a little further.
