OEIS Sequences

q-factorial numbers 3!_q. A69778

Numbers k such that k | 13^k + 13. A15905

Trajectory of 13 under the '13x+1' map. A57684

a(n) = ∑_k=0..n (3·n-2·k)!/((n-k)!³*k!)*(-2)^k. A318109

Numbers m such that 18·m + 1, 36·m + 1, 108·m + 1, and 162·m + 1 are all primes. A372188

Consider the trajectory of n under the iteration of a map which sends·to 3x - σ(x) if this is >= 0; otherwise the iteration stops. The sequence gives values of n which eventually reach 0. A37159

Sum of n-th antidiagonal of array in A081998. A82001

Irregular triangular array read by rows: T(n,k) = number of non-isomorphic unlabeled connected graphs with loops on n nodes and with k edges. A283755
