Coolio, guess I'm a Titan now.

I know, that term is very outdated... Hell outdated doesn't cut it. I'm hereby inventing the term "log-outdated". ;)

Thanks for the info.

Speaking of the Stone Age; isn't it a little weird that we can't attach *.rar files? Had to choose *.zip.

The main machine is back in business, pretty much...

Except, the wise man who repaired it forgot the fan.

Luckily, there seems to be a second fan.

Hope you don't burn anything... =S

But I'm under the impression that you've owned a computer before, so I guess things will be fine.

((((((892588087^2-12)^2-98)^2-122)^2-12)^2-110)^2-60)^2-138

1146digit prime

Prime after each subtraction. (digits;18, 36, 72, 144, 287, 573, 1146)

Hmm.. I wonder what category that might fit in with..

I think it fits in w/General arithmetic progressions.

Yep. Lorgix's item is a #19 item, and I think comes in second place for the #19's largest primes category.

I have one similar to Lorgix's..

Though, I'm going to avoid Primo. It would take years to prove it prime.
