Still on the way down, and almost at 170 digits now! :)

Woohoo - below 170 digits now!



P.S. I hit refresh on the factordb page several times a day watching this number go lower and lower

Now below 160 digits!

And yes, I am also checking the status multiple times a day.

There are two things that one never tires of watching:
swimming women and other people working.

Wrote a small program to help automate my main factoring script and posts to factordb.com, so the updates should come a bit more quickly now. :)

And so we are below 150. Soon this will become fast, and hopefully until the end!

Is the number of values less than a million available that are known to be attached to the 4788 genealogy tree? I see from http://www.mersenneforum.org/showpos...7&postcount=65 that 1022 sequences are in that tree but I think those are the sequences that always stay below a million. I think there are more that sneak above a million and then come back down or grow much larger and come back down like 314718.

I guess I'm wondering about getting a sense of the odds, if the sequence falls below a million again like 314718 did, that it will intersect itself to make a sociable cycle with thousands of numbers in it.

well using: http://factordb.com/aliquot.php?type=1&aq=4788&big=1 to figure out the values in the sequence as calculated form 4788 I got:

Checked 0 4 (show) 4788 = 2^2 · 3^2 · 7 · 19
Checked 1 4 (show) 9772 = 2^2 · 7 · 349
Checked 2 4 (show) 9828 = 2^2 · 3^3 · 7 · 13
Checked 3 5 (show) 21532 = 2^2 · 7 · 769
Checked 4 5 (show) 21588 = 2^2 · 3 · 7 · 257
Checked 5 5 (show) 36204 = 2^2 · 3 · 7 · 431
Checked 6 5 (show) 60564 = 2^2 · 3 · 7^2 · 103
Checked 7 6 (show) 105420 = 2^2 · 3 · 5 · 7 · 251
Checked 8 6 (show) 233268 = 2^2 · 3 · 7 · 2777
Checked 9 6 (show) 389004 = 2^2 · 3 · 7 · 11 · 421
Checked 10 6 (show) 745332 = 2^2 · 3 · 7 · 19 · 467

however for intersections with other sequences would take the merge thread and a few more at least probably.

Checked 0 4 (show) 8092 = 2^2 · 7 · 17^2
Checked 1 4 (show) 9100 = 2^2 · 5^2 · 7 · 13
Checked 2 5 (show) 15204 = 2^2 · 3 · 7 · 181
Checked 3 5 (show) 25564 = 2^2 · 7 · 11 · 83
Checked 4 5 (show) 30884 = 2^2 · 7 · 1103
Checked 5 5 (show) 30940 = 2^2 · 5 · 7 · 13 · 17
Checked 6 5 (show) 53732 = 2^2 · 7 · 19 · 101
Checked 7 5 (show) 60508 = 2^2 · 7 · 2161

Checked 1827 6 (show) 543242 = 2 · 7 · 38803
Checked 1828 6 (show) 388054 = 2 · 194027
Checked 1829 6 (show) 194030 = 2 · 5 · 19403
Checked 1830 6 (show) 155242 = 2 · 77621
Checked 1831 5 (show) 77624 = 2^3 · 31 · 313
Checked 1832 5 (show) 73096 = 2^3 · 9137
Checked 1833 5 (show) 63974 = 2 · 29 · 1103
Checked 1834 5 (show) 35386 = 2 · 13 · 1361
Checked 1835 5 (show) 21818 = 2 · 10909
Checked 1836 5 (show) 10912 = 2^5 · 11 · 31
Checked 1837 5 (show) 13280 = 2^5 · 5 · 83
Checked 1838 5 (show) 18472 = 2^3 · 2309
Checked 1839 5 (show) 16178 = 2 · 8089

came up after searching a bit of the merge and termination thread.
