Properties

Appears in sequences

• Sophie Germain primes p surrounded by Sophie Germain primes.at n=3A171161
• Define Sophie Germain isolated primes to be primes p such that 2p+1 is also prime and so that p-2 and p+2 are not primes. The sequence contains Sophie Germain isolated primes p such that the previous prime to p and the succeeding prime to p are both also Sophie Germain isolated primes.at n=0A171162
• Smallest prime(k) such that the concatenation prime(k)//prime(k+1)//...//prime(k+n-1) represents an emirp.at n=11A173448
• Prime numbersat n=9902
