ORLANDO, Florida - December 2, 2003 -- Michael Shafer, a 26 year-old

volunteer in the Mersenne.org research project called the Great Internet

Mersenne Prime Search (GIMPS), has discovered the largest known prime

number. Shafer used a Michigan State University lab PC and free software

by George Woltman and Scott Kurowski as part of an international grid of

211,000 networked computers in virtually every time zone of the world.

The new number, expressed as 2 to the 20,996,011th power minus 1, has

6,320,430 decimal digits and was discovered November 17th. It is more

than two million digits larger than the previous largest known prime number,

and belongs to a special class of rare prime numbers called Mersenne

primes . The discovery marks only the 40th known Mersenne prime, named

after Marin Mersenne , a 17th century French monk who first studied the

numbers 300 years ago.

--- Dear Antreas,

Thank you very much. Earlier today I was preparing my number theory notes

for the coming semester,

and was checking the record of Mersenne primes. I came across this in Chris

Caldwell's page who

indicated that the record is from 2003. I did not realize that it is as new

as today!

Best regards

Sincerely

Paul

Of course I have not read it carefully. It was discovered 2 weeks ago.
