Odds and ends....and class records

Darn the luck! 689652 just picked up a 3 so it won't stay where it's at, but check out the graph for the last ~100 lines!

The thees come and go... as long as no 7, everything is fine

I got a down-driver at 147 digits (829332:3098) on 9 January 2014 and rode it down to 98 digits (829332:3315) today when the downdriver was lost.

Just realized no one else posted about this. 4788 is now the highest sequence computed so far and is not driver controlled. It is at 195 digits, edging out 3270 by 2 digits:

Also, you have to go all the way down to 179 digits to find a non-driver controlled sequence and all the way down to 169 digits to find one that is both non-driver controlled and does not have a 3 in the guide....

It might be nice to try to be the first to 200 digits.

I just realized after checking Wolfgang's page that with the last termination we are one away from bringing the total open sequences below 1M down to 9200. If you check the earliest capture in the Wayback Machine (June 19, 2005) there were a total of 9474 open sequences below 1M then.

I've 9197 in my list. Can you post yours for comparison?

See the current list here. It should be completely synced with Wolfgang's count.....

167358 just lost its 28th downdriver. Well, I'll torture it some more (currently with "2 * 3", up from i2411 to i5984)

[Batalov]

Bah! Hambug!
My minions are drilling on three downdrivers at once (I saw two before, three is rather rare)

I just discovered that fivemack is one C175 away from being the first to take an aliquot sequence over 200 digits.

http://factordb.com/sequences.php?se...&action=last20

The next term will have a log10 of 199.2866, meaning 200 digits starting with the following: 19,347,049,672,300,256...
