reserving 817212 and 817662

Just some interesting (to me) trivia:
 

[URL="http://factordb.com/search.php?se=1&aq=805710&action=last20&fr=720&to=800"]805710[/URL] has been hanging on for quite a while and even running long spans of up to 22 iterations for a single length. One especially interesting bit came to light as I was looking over some of the lines - i774 and i775 are identical for the first 35 digits.
[code]
i774: 16120196721675589380953223003255835427015998963380473406993203299213557627682432535666069773364816
i775: 16120196721675589380953223003255835733319719299374624451619369678789564698209713306820023452842928
[/code]OK, I'll go back to my corner and be quiet now...

When a sequence has a perfect number driver, when the smallest prime factor not part of the driver is large, the next line is only very slightly larger. The most extreme example of this is when a line factors as 2 * 3 * prime: the next line is only 12 (and yes I mean 12) bigger.

Also, you can get much longer stretches with the same digit height when a sequence has the 2^3 guide, which is like the downguide (2^2) but it can't drop sequences as much and it has more factors which will cause an increase, meaning that it has a tendency to stay at the same height. It can't pick up a 3 like 2^2 either. I think I have had a run of nearly 100 lines at the same height with 2^3 at about 60 digits after a downdriver run.

51/78 890k sequences now finished. The graph now looks much more interesting with the early-soarers all gone.

897204 had the most interesting path of anything that's finished.

Done with 809256, 106 digits, 2^2*3*7
Done with 809292, 105 digits, 2^2*7
Keeping 809352 at 116 digits as it has no driver (2^4*3*5^2)

Be sure to get the newest file from the DB for that, as I've (very recently) been playing with that sequence to try out the new stop-on-large-composite feature of aliperl.pl, and in the process brought it up to 85 digits.

Reserving 815780.

I did that - got the file from the DB just after I had posted.

895230 terminates with prime 41

59/78 sequences now finished processing: 1 termination, 58 at 100 digits.

815780 done.

Done with 809424, 101 digits, 2^2*7
Done with 809640, 101 digits, 2*3

Reserving:
816360, 816672, 816792, 816822, 816876
