Beautiful! Congrats!

P.S. What's with the magnifier? :shock:

Congratulations indeed.
Hope it's a good milestone. Not least because both Nick and I achieve the same in just over a month.:smile:

Hope it's not to read the amount on the birthday cheque!

I found my first MEGA prime:

13*2^4998362+1

and I got it before PrimeGrid in a range they haven't gotten to yet.

If it is proven on the Prime Pages (llr says its prime) it will be #37. The GFN divisibility check is going to take some time.

Congrats!

(For GFN tests, you can leave the default process running and, on a side, run a few quickies: with options -gos2, -gos3, -gos5 etc.)

P.S. Right at the end of the range (4.5-5M), too! Worth the wait, though.

I was running PRPNet and I ^C'd in the middle of the GFN test and didn't even notice that it was prime. I wasn't expecting one considering this was the last day of testing for the range I had reserved.

I can run the Fermat divisibility test for you in under an hour (I've written a parallelised version of mprime for this particular task). Current state
[CODE]Iteration: 550000 / 4998362 [11.00%]. Per iteration time: 0.001 sec.[/CODE]

That's okay. It will finish when it finishes. I'm in no hurry.

The k is small, and you have 42 xGF lotto tickets!
~3 of them will win, but we cannot know which. ;-)

Good luck!

[QUOTE]With the understanding that foreign markets, especially the Asia-Pacific region, are the key to generating millions of motorcycle sales on annual basis, I offer this challenge: Can you guess which motorcycle brand is the world's top seller?[/QUOTE]

They sold us another one three weeks ago.
