Properties

Appears in sequences

• a(n) = prime(2^n + 1).at n=13A051439
• Smaller of two consecutive primes whose sum is a square.at n=26A061275
• Initial term in sequence of four consecutive primes separated by 3 consecutive differences each <=6 (i.e., when d=2,4 or 6) and forming d-pattern=[6, 6,2]; short d-string notation of pattern = [662].at n=34A078857
• Primes p such that the differences between the 5 consecutive primes starting with p are (6,6,2,6).at n=14A078965
• Smaller member of a prime pair (n, n+6) with a square sum.at n=6A086776
• Lesser of consecutive primes whose sum is a perfect power (A001597).at n=32A091624
• Primes of the form 16*k-1 such that 4*k-1 and 8*k-1 are also primes.at n=32A101793
• Numbers m such that Conv(b,m) = b has a unique nontrivial solution (b = 0 and b = 1 are considered trivial solutions). Here, Conv(b,m) denotes the limit of b^^t (mod m) as t goes to infinity.at n=36A347561
