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=14A065505
• Primes of the form ((p+1)/2)^3 + ((p-1)/2), p is prime.at n=10A163426
• Primes of the form n^3 + n - 1.at n=16A182332
• a(n) = (2n-2)^3 + (2n-2) - 1.at n=26A255877
• Number T(n,k) of permutations of [n] with exactly k distinct lengths of increasing runs; triangle T(n,k), n>=0, 0<=k<=A003056(n), read by rows.at n=28A317327
