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.

:-))))))))))))))))))))))))))))))

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
