Properties

Appears in sequences

• Group successively larger prime numbers so that the sum of the n-th group is a multiple of n. Sequence gives the group sum divided by n for the n-th group.at n=38A074131
• Second prime factor of x = 3^p - 2^p when p is prime and omega(x) >= 2.at n=18A089163
• Smallest prime p such that p^n is equal to the sum of 3 consecutive primes.at n=45A122706
• Primes p dividing every A167859(m) from m=(p-1)/2 to m=(p-1).at n=34A167860
• n-th prime p such that (p+n)^2+n is prime but (p+j)^2+j is not prime for all 0<j<n.at n=26A238663
• a(n) is the smallest odd prime that divides (-n) + the sum of all smaller primes, or 0 if no such prime exists.at n=19A274995
• Primes such that A271229(n) = prime(n).at n=35A276649
• Primes equal to a heptagonal number plus 1.at n=25A285791
• Prime numbersat n=3097
