I knew it the second I hit submit and so submitted another correctly right after. It's the 2nd time I've done that in 15 years. :-) Not too bad I guess. Looks like it's been permanently deleted now. Unfortunately there is no "delete" once you hit submit even though it hasn't started primality testing yet. That would be a nice feature.

VBCurtis at RPS has searched k=405 on-and-off for many years beginning a little before NPLB was started. Coincidentally he happened to find the prime shortly before you did.

Congratulations!
I know how I felt when Prime95 start making buzzing sound :)

Congratz kruoli,
That's 300k+ more than just a mere Megaprime. Let's hope that the Top-5k site endures to keep the scores. :smile:
