      Hi to all,

      As our own Phil Carmody and David Underbakke are breaking twin prime
      world records I thought I might try and break the record for the most
      easily memorised large prime.

      PrimeForm Output.

      (800^4)^2+1 is probable prime! (a = 17021) (digits:24)
      (800^4)^2+1 is prime! (by Proth's Theorem) (verification : a = 17029)
      (digits:24)

      A prime to remember! 800^8 + 1 = prime.

      (Of course, this is called the "One over the eight" prime)

      Anyone claim to beat this ! Is there a list of easily memorised
      primes?

      regards,
      Paul Mills

        Hello!

        There are many yet more "memorable" primes at
        http://www.utm.edu/research/primes/curios/

        And the prime
        1022003330004444000055555000005555500004444000333002201
        is also memorable.

        Best wishes,

        Andrey

          You haven't looked at Prime Curios collection!!!
          http://www.utm.edu/research/primes/curios/122...221.html

          The prime 122334444555554444333221 is the second number I
          sent to G.L.Honaker who keeps this nice collection. (The
          first number was 123456789ABCDh in hexadecimal). At all,
          I've already sent 75 numbers there! :-)

          I've noticed the number
          1022003330004444000055555000005555500004444000333002201
          only because it's absent in Prime Curios collection. This is
          3rd number I sent to G.L.Honaker, but he didn't published
          it. :-(

          The first new prime in 3rd Millenium was
          9^8+8^7+7^6+6^5+5^4+4^3+3^2+2^1+1^0,
          this is one of my favourite primes, see
          http://www.utm.edu/research/primes/curios/45269999.html

          Sure, there are many primes which beat your record!

          Best wishes,

          Andrey
