10 digit prime in e
 

This story made the news recently:
Has anyone else heard of it?

This sound like a good idea for RMA 1.7!
L9 has the largest data-base of unsubmitted titanic primes.
There are a few worthy of a contest like this, and ofcour$e prize.

The URL on that billboard doesn't work.

It is the purpose of that billboard that only those people who understand the problem and solve it can get this url.

Find the first 10 digit prime in e and paste it into the url. [url]www.yyyyyyyyyy.com[/url] and not the question itself.

Actually there's another competition running concurrently - here's another billboard that's up in Silicon Valley at the moment.

NNNNOOOOOOOOOOO!!!!

The Google puzzle has expired and is no longer accepting responses. Thank you for your interest and participation.

And I never got to see what happens next...

But maybe... I could create my own challenge like that, and challenge people I know! Does anyone know how I can create my own domain name?

First odd perfect number:
This one is kind of joke.
If there exists a odd perfect number it has surely some hundred prime factors (I don't know how many the proven lower limit is), but the number itself would have (at least) thousands of digits.

URLs are quite limited here.

Current proven limit seems to be 47 factors. Check out the factoring thread.

Again, please, does anyone know how I can create my own domain name so I can build my own series of challenges like that? And maybe some sites that will let me create user accounts (like the Google challenge did for Linux.org)?

I run ElevenSmooth.com for $7/year using "free" web space from my ISP. Information is included in the ElevenSmooth FAQ starting here

But it is possible to get a domain name for free? Or am I just asking for too much?
