The 25th and 26th Mersenne Primes
Copyright policy )The 25th and 26th Mersenne Primes
The 25th and 26th Mersenne primes are 2 21701 − 1 {2^{21701}} - 1 and 2 23209 − 1 {2^{23209}} - 1 , respectively. Their primality was determined with an implementation of the Lucas-Lehmer test on a CDC Cyber 174 computer. The 25th and 26th even perfect numbers are ( 2 21701 − 1 ) 2 21700 ({2^{21701}} - 1)\;{2^{21700}} and ( 2 23209 − 1 ) 2 23208 ({2^{23209}} - 1)\;{2^{23208}} , respectively.
