P.C. Poops Latex

In mathematics, Euler's identity (also known as Euler's equation) is the equality

e^ i*pi + 1 = 0


Let´s transform this a little bit:

add 1 on both sides and square the whole thing.

ya thanks I am fully aware of this, but still searching for a primality test available, maybe LL-like with Lucas sequences.

Is there a program which can perform such a primality test on RepUnits?...

..... and if u really wanna help me, please provide more info than "Read Knuth´s book" a la RDS ...

To be more specific, we are dealing with numbers of the form (10^n-1)/9
thanks

All primes (except 2 and 3) are of the form either 6n-1 or 6n+1, that is nothing new.

However, what´s interesting is:

What makes these 8 numbers (if they are complete) so unique?

Another interesting pattern of Mersenne exponents: they are prime!!!!1111

Mersenne prime exponents (except 2 and 3) follow this "pattern", or however you may call it.

There are 2 strands, the 5-strand and the 7-strand. (6n-1 and 6n+1)

Furthermore there are 8...

Maybe sure was the wrong word.

But I see a strong correlation between Mersenne prime exponents, Sophie-Germain Primes and Twin primes.

And of course q = 2*p+1, not 2*p-1, as I posted before!

No, only p is a SGP, not q. Sorry for mixing this up!

Nevertheless, can q yield a Mersenne Prime?

Sophie-Germain primes as Mersenne exponents

Suppose, an exponent p (1 mod 4) yields a Mersenne Prime Mp=2p-1.

If q = 2*p-1 (3 mod 4), will the resulting Mq be composite? If yes, why?

q is a Sophie-Germain prime.

Thanks in advance!
