This is the info on the prime in question from SB (17 or bust).

we began to wonder when our own next discovery would come.

Long have we waited. And now, at last, the waiting has paid off.

5359*2^5054502+1 is prime!!!

On 6 December 2003, at 3:42:02 PM EST, the 1,521,561-digit prime was reported to the server. Due to the size of the number, it took 7 days to verify. The number weighs in as the 4th largest prime ever discovered. The story of the lucky participant, Randy Sundquist [stats], fits well with the discovery's timing:

"The prime was found on a computer I made out of old parts for my sister, who is going to school in Madison, WI. I installed the client to test the machine for a few days. The first and only work it did resulted in the prime!"

Randy is the founding member of Team ExtremeDC and has been crunching SB for over a year. He sometimes runs up to 20 SB client machines. The lucky machine he built for his sister is an 800 MHz Duron with 256 MB of RAM. This machine completed the Proth test in 10 days and 20 hours.
