Funny looking number
First off, i'm sorry if this is the wrong location for this; But it seemed right by the name.
So, today i was messing around in python with the prime i got "77536897". I decided to do some test with my lowend prime program i wrote. I realized that 7753689^7 gave me 1684839914110098939787407853082536973852201202729 which in itself is too a prime number. Both 7753689 and 7536897 are too prime numbers. My program was not able to find 7^7536897. But i am sure that anyone may find interest in this number as i have. i will look for other numbers as well to insure not just a glitch in the matrix... i just did some little investigation on 7536897^7, which ironically gave me 1381491004566552667414465552862865977844679968513. ANOTHER ONE

7753689 is not a prime, it is 3^2 * 31 * 27791. 7753689^7 is certainly not a prime  in general n^7 is never a prime for any integer n. Similarly, 7^7536897 is not prime  it's divisible by 7.

Charles,
When confronted with such blatant symptoms* of crankiness I do not understand the urge to respond. There is not much hope of reaching a rational argument. Jacob * The huge fonts, the claim that an integer elevated to an integer power would be prime... It even looks more like a troll, who are to be fed, than a crank.
