81882 more than doubled in length with more than 5 up-downs... until this calamity cut its (future) life fairly short:

Well, c'est la vie...

However, totally unrelatedly, another sequence seem to have moved up to become the third longest sequence... and it is still quite unstable...

DB or it didn't happen. (btw:- 81882)

Quite a lucky escape from such a nasty driver that seemed to spell certain doom for such a long and interesting sequence!
Best of luck with 81882! May it terminate quickly.

[gd_barnes]

I extended 19380 a few indexes but am not reserving it. Status:

19380, i=1846, sz 125, C104, +4, 2^2

Somebody might like this one. In the 4 indexes that I extended it, I lost the factor of 3!

Here are some sequences that I'm not reserving that are higher than what is shown on the pages (I didn't extend them):

15960, i=2033 (already terminated)
19494, i=1448, sz 106, C95, +3, 2^6*127

Here is one that I inadvertantly extended a little bit before realizing it was reserved by Clifford:
19852, i=856, sz 111, C105, +7, 2^3*3

Did you find the p42*p74 by ECM or GNFS?

Well, it is a bit scary, because even though it has got 2³*3*5 now, it is now only c97 at iteration 7922... this is definitely the new longest sequence. 8000+ is around the corner.

That'll overhaul 389508, 2nd place in the merged sequences list...

...and could 314718 be under threat?

After a very hairy c137 (13 days......my biggest job ever!) I got this break on 167148 (very nice: p56*p82):

Maybe 4788 will manage the same thing!

And my hat's off to mataje for managing the escape from at 135 digits!!

ECM in one of the last few curves as I recall. I'm still not messing with GNFS yet hence why I only continue to a hard factor of C<=100 with a notable exception of sequence 19278, which is quite interesting.

I am now done with 183680. I took this one quite a ways but was unable to get rid of the perfect number 2^6*127 factorization. Status:

183680; i=1559; sz 114; C105; +111; 2^6*3^2*127
