• Partial sums of A001891.at n=17A053808
• a(n) = A000045(n+6) - (n^2 + 4*n + 8).at n=19A163250
• Triangle read by rows: T(n,k) is the number of permutations of [n] having k adjacent cycles (0 <= k <= n). An adjacent cycle is a cycle of the form (i, i+1, i+2, ...) (including 1-element cycles).at n=47A184184
• Smallest number k such that k*n +/- 1, k*n^2 +/- 1, and k*n^3 +/- 1 are three sets of twin primes. a(n) = 0 if no such number exists.at n=6A239021
