2^2-1=3 is prime, the first position is 1, 4 is not a multiple of 3

What's the big deal? There is another prime number a million times longer than that one.

Also something about primes: I wonder if, for any prime P, 2^P -1 is a prime or not? For example, for P = 3, a prime number, 2^3 - 1 = 8 - 1 = 7, which is also prime, but if P = 4, NOT a prime, 2^4 - 1 = 16 - 1 = 15, which is also NOT a prime.

I would think the first check is: does it end in 0, 2, 4, 5, 6, or 8. If so, not prime.
Of course that is for polydigit numbers.

Primes like other numbers don't 'exist in the world''. They are abstractions. In this sense, mathematicians haven't found the number 2 yet. And they never will.

I thought, that 2^(2^(2^x-1)-1)-1 is always a prime as long as x>1?
E.g. for x=2 it is 127, for x=3 it is 170141183460469231731687303715884105727 etc...

I love to look at those prime numbers too. I had a spreadsheet I worked out with sieve. It grew so large I could hit the send button and go in and pour myself a cup of coffee shuffle on back onto the computer sit down drink part of the coffee and wait. If I had set things up right it would tell me if the number I was testing was prime. If I had not set things up right it would say circular reference. What a huge circle to be a circular reference

I was once told of another way to check if a number was prime. Square it and subtract one, and if it is divisible by 24 it is prime. e.g. 5 squared = 25. 25-1 = 24 /24 = 1 7 squared= 49. 49 - 1 = 48 not sure if it will be completely bulletproof tho

With a, b, n being natural numbers and a>b, we have
1. If (a^n-b^n)/(a-b) is prime, then n is prime.
2. If n is odd and (a^n+b^n)/(a+b) is prime, then n is prime.
