My daughter is totally nuts about British wildlife; especially badgers. Tonight we went to some local fields and found a badger sett! We saw two adults and two cubs. She's named them Alpen, Special K, Dennis and Gnasher. (I can't believe they didn't run off because of the racket we were making.)

She's bouncing of the walls with excitement. Let me out!!!

90th percentile ECM
 
44th lifetime out of 445.
39th last 365 days out of 431.

One more to go.

So it was caught in Stage 2, I suppose. I forget what B2 was, but I had given it quite a bit of memory, so probably at least 5M. A B2 of half that would have caught this one.

Congratulations. I specialize in this type of work, and the biggest I've had was just 103 bits.

wahoo! Its done! My slowest double check ever, assigned 222 days ago. Completed by a 333 Mhz Celeron laptop. 21446693 and it matches correctly too.

I'm sure there are some that took lots longer, anyone know what the slowest successful LL run has been?

I'm guessing several years. A long time ago, a forum user called GP, who has long since stopped posting, wrote about long-running LL tests. You might want to search for his old posts.

[CODE] Type Rank of GHz days Count
TF 1245 4746 1.3708 238
P-1 784 3746 24.6167 10
LL 329 2794 785.9132 14
LL-D 125 1440 517.1937 30

Passed 6K GHz days.

Here's another one...
 
M50793667 has a factor: 13665343899939230037984875767. "Only" 93-and-a-half bits this time, but still quite impressive. And it's always nice to "kill" these bigger exponents without an LL.

c54 = p26.p29

M8764207 has a factor: 947498223819695387398090449211913249807953123422721673
[/code]180 bits... :tu:
