[QUOTE=dabaichi;310400]Are there any exponents below 43112609 that only have suspect LL result(s)? Do they count as "tested at least once"?[/QUOTE]

To the best of my understanding (based on empirical observation, not access to the code), no to your first question. I don't think so to your second.

Primenet appears to immediately re-issue any candidate LLed with an error code as another LL. If the residues match, then the candidate is cleared. If they don't match, but the second LL came back "clean", then the candidate goes into the queue to be DCed (years) later.

Thanks for your answer!

[QUOTE=chalsall;310386]Yup... Our "friend" Signals has been busy....[/QUOTE]

Wonder if he is related to our other "friend" in the 25M DC range. :confused:

Ha ha, you beat the guy by two days! I love this! :cool:

I wonder if Signals will continue to contribute at his present rate, albeit in a more polite fashion. You've got to admit, he wiped out quite a few LLs in a relatively short space of time (something like 12-15 in 2-3 weeks, I think).

And should Signals be an alias for a known GIMPSter, I wonder if he/she will ever reveal their identity, LOL. Of course, there is the risk that they might be impoached for their peaching. :judge:

In any event, though we may have arrived at the twin milestones by less-than-kosher activities on Signals' part, it is still worth a hearty [B]CONGRATULATIONS GIMPS!! :toot::toot::toot::maybeso::bounce wave:[/B]

Is this the first time in GIMPS history that "First-Time LL" [I]strictly[/I] implies "World Record LL"?

Argh! :lol: (I had to attach the other smily I wanted to use.)

No, it's the 3rd time, but it's 11 years since last time:

Just verified another DC with CuLu on the GTX 460. Small beans, I know. But at least one card runs it. It has yet to produce a mismatch.

First time all expos lower than the record have been tested since the first million digit prime.

Now we can concentrate on finding another milestone (i.e. another Mersenne prime)
ETA currently 2018.
