Appears in sequences

• Mersenne exponents: primes p such that 2^p - 1 is prime. Then 2^p - 1 is called a Mersenne prime.at n=44A000043
• Bisection of A000043.at n=22A099982
• Mersenne prime indices that are also Gaussian primes.at n=18A112633
• Primes p (A000043) such that 2^p-1 is prime (A000668) and congruent to 607 mod 6!at n=4A145045
• Isolated primes p such that 2^p-1 is also a prime number.at n=28A161676
• Prime numbers n such that 2^n-1 is a prime that cannot be written in the form a^2+7*b^2.at n=21A216519
• Odious Mersenne exponents.at n=24A237499
• Numbers m such that 2^m + (-1)^m is prime.at n=48A285929
• Let M_p = 2^p-1 be a Mersenne prime, where p is an odd prime. Sequence lists p such that b_{p-2} == 2^((p+1)/2) mod M_p, where {b_k} is defined in the Comments.at n=22A354167
