I just found my largest prime ever, 1354828*2^1354828+1 (407850 digits). It is a Cullen prime, in the form k*2^k+1. It is the largest known of that form and comes from many months of primality testing. Even better yet is that it is the largest prime found with help from a version of my MultiSieve program that I ported to PowerPC.

I think a few bananas would have been in order there Rogue, well done.

My 1000th post at mersenneforum.org :mellow:


(Hmmm ... starts a new page, too. On a Hollywood Stock Exchange forum that would be worth something, but here it's too easy.)

With the latest update, I have now climbed to #786 for LL testing in all of GIMPS!

I've borged my dad's new notebook (not until 2 days after he bought it, sorry :redface: )

It's a Pentium M with 2.13 GHz, 1 GB RAM (I didn't know 1 GB RAM was possible on a laptop) and a gigantic screen (by notebook standards).

Mine is over a year old and has 2GB of RAM :banana:

Doing LL or factoring? Asking because Pentium M's simply dominate on everything in factoring.

After long time of pause I start doing LLs again. It brings back nice memories and it feels good. :smile:
