NB 1. If the #Mersenne number M_n=2^n-1 is prime (in which case M_n is called a Mersenne prime*), then n is prime. The converse is generally not true (eg M_n isn't prime for n=67). 2. It's only conjectured that there're infinite number of Mersenne primes.

Cont.) This is the full list of 12 primes n less than 257 for which the
#Mersenne number M_n is prime: n = 2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, 127. Considering 1 as a prime, M_1 = 1 is also prime. The next prime n following 107 for which M_n is a Mersenne prime, is n = 521,Thanks. Twitter will use this to make your timeline better. UndoUndo

What is the significance/application of this no in real world?

I don't understand how a follower of this account doesn't understand that most number theory doesn't have immediate applications, yet, the discoveries & understandings that arise can have profound effects in the future, beyond the important understanding of Math & Science better.

Don't worry,
@standupmaths will be doing this as an encore at his book signings for Humble Pi next year. We assume...
