US mathematics enthusiasts found that the maximum number of people is more than 7 million

This number of 7 million copies can be written to 24036583 minus 1. This is the number 41 Mason pop-up discovery.
According to the "New Scientist" magazine website, the mathematics enthusiasts named John Fen De Li joined the "Internet Mason Sui Search" (GIMPS) activities five years ago, he also used This ordinary desktop discovers this prime number. Before I officially announced this news on May 30, he also spent two weeks of time for verification. The two other volunteers who have the "Internet Mason" activity in France and Canada have also confirmed the discovery of Fende. And in half a year ago, a student in the United States found the number of number 40 Mason, which had a total of 63,20430 digits.
The number of prime is also called the number, which is only the number of herself and 1, for example, 2, 3, 5, 7, 11, etc. 2,500 years ago, Greek mathematician Ou Sirid proved that the number of prime is unlimited, and a small number of prime numbers can be written as "2 N times to reduce 1", and N is also a prime number. Since then, many mathers have studied this number of prime numbers. The 17th century French priest Mason Messen is one of the fruits of outcomes, so the number of "2 N times minus 1" form is called Mason.
In 1995, the US program designer George Watman organized the number of Mason's number of Mason, which has prepared a Mason's calculation procedure, and placed it on the Internet for math enthusiasts. This is the "Internet Mason Suo Search" plan . There are currently more than 60,000 volunteers, more than 200,000 computers are involved in this plan. The plan takes a distributed computing method, using a large number of ordinary computers idle time, and obtains the calculation capabilities of the supercomputer, and the number of thirds, 37, 38 and 39 Mason use this method. A Foundation of the United States also set up a $ 100,000 bonus to encourage the first person to find more than 10 million people. (Finish)
