Properties

Appears in sequences

• Let p(k) denote k-th prime; consider solutions (p(n),p(m)) of Diophantine equation p(p(n)+1)-6.p(p(m))=1 (*), where p(p(n)) belongs to A060213 and p(p(m))=(p(p(n))+1)/6; sequence gives values of p(n).at n=6A065505
• Primes of the form prime(i)*prime(i+1) + prime(i+2) + 1.at n=16A180945
• Primes of the form k*(k+2)/3 - 3, k>2.at n=41A262203
• a(n) = 137*n^2 - 4043*n + 27277.at n=35A267706
• Number of unlabeled connected multigraphs with n edges, no cut-points and degree >= 3 at each node, loops allowed.at n=12A360882
