Abstract: The 25th and 26th Mersenne primes are $ {2^{21701}} - 1$ and $ {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}}$ and $ ({2^{23209}} - 1)\;{2^{23208}}$, respectively.
