I'm going to see how high I can take this for now currently working on i948 sz. 130 = 2*3*C129 right now.

just as an update I'm now working on line 985 about 160 lines from when I started it, now size 131 with a C120 cofactor. it's been driver 2*3 almost the whole time I believe

It is now at < 60 digits in size in the DB and all seqs were up to > 110 digits. So there is definitely something wrong with the DB.?

Does anyone have any evidence that 985596 was ever at 110 digits (or terminated/merged)?

It doesn't show up in a search of the forum, so it was never included in any 100-digit or 110-digit subproject. And it's not the the list of open sequences that my workers have been tracking for the last year.

So either it was terminated/merged more than a year ago and is now missing from the DB, or it somehow got overlooked all this time. I'm not sure which is more unlikely.

There is definitely something wrong with the db.

My script happily runs 985596 from iteration 1 to iteration 1491, at which it stops, in about a minute on one 2GHz Athlon64.

Comparing the output with the db:

(db)

Checked 731 21 (show) 745712356057859328544<21> = 2^5 · 7^2 · 490889183 · 968817151
Checked 732 21 (show) 962102102235363155150<21> = 2 · 5^2 · 7 · 420047 · 1804937 · 3625711
Checked 733 22 (show) 1083058646835105174322<22> = 2 · 11 · 23857 · 323797 · 6372951919<10>

(me)
Code:
   731	   745712356057859328544=2^5*7^2*490889183*968817151
   732	   962102107477168600544=2^5*7*37*3769*5483*25633*219143
so sigma(N) has been mis-computed at line 731; pari-gp agrees with me.

The mis-computation is exactly what you would produce if you believed 475581859730777633 (= 490889183*968817151) to be prime.

I've told syd.
