My first "real" termination here:


13^98 terminates at term 1448 with prime=43 after starting at 110 digits!

Perhaps there're more errors there after last offline/update, only checked for n=2 and 3 yet.
What can we do about it ?
Is it possible to correct this on DB ?




Thanks gd_barnes, I will update the next weekend.

In the larger sequences that begin at > 105 digits, I found several down drivers. I ran those until they were gone. Many had very wild rides. One terminated. Here are the updates:

10^109: 587 U115 (109) +582 iterations
10^113: 455 U104 (97) +451
10^117: 1215 U108 (105) +1211
12^107: 1378 U107 (99) +1371
12^109: 333 U112 (109) +331
13^98: 1448 U2 (2) +1445 (terminated as previously reported!)
13^106: 171 U103 (101) +160

Most of these were already updated before I reported them.

Thanks to all.

Note :

By me, 3^152, 3^154, 3^156, 3^162, 3^168 at 120 digits or more.
3^164 terminated after 2595 iterations at a P3.

Now, in the power table of 3, we can see an isolated white cell : 3^108.
kar_bon had reported this error on DB, a few posts above.

I don't understand what's going on.
I restarted the calculation on my computer, my program is not wrong though !

I don't know how to correct the mistake !

You can't do anything here, Syd has to correct the database entry.

I've attached the corrected ELF-file for seq. 3^108: it's at 122 digits now with 2^6 * 127 driver.

To handle this in the scripts:
- copy the "108.htm" from the zip into the 3-folder (it's not correct in the factorization but in digits/index count)
- insert "rem " in front of the line for 108.htm in the "run4_get.bat" to suppress the download for this seq. (change again after calling "run3_make_download.bat")
- create data for this n as usual

If Syd corrected the database, everything will fine again.
