Properties

Appears in sequences

• Smaller term of closest safe prime pairs.at n=21A059323
• Special safe primes (from A005385) such that the next prime is also a safe prime.at n=9A059394
• Smaller of safe prime twins: special safe primes (A005385) p such that the next prime is also the next safe prime and is p+12, i.e., occurs at the closest possible distance, 12.at n=7A059395
• Primes of the form 16*k-1 such that 4*k-1 and 8*k-1 are also primes.at n=21A101793
• Number of polyominoes consisting of 6 regular unit n-gons.at n=24A103472
• Primes p such that p^3 - 1 has 8 divisors.at n=39A341659
• Primes p such that p^9 - 1 has 16 divisors.at n=3A342065
• 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=25A347561
