- Second-order Eulerian numbers: a(n) = 2^n - 2*n.at n=24A005803
- a(n) = 4^n - 4*n.at n=12A107584
- Sequence S with property that for n in S, a(n) = a(1) + a(2) +...+ a(n-1) and for n not in S, a(n) = n+1.at n=43A121173
- E.g.f.: (e^x - x)^2.at n=24A130102
- Partial sums of A000918, starting from index 1.at n=22A145654
- If an array is made of columns of -nacci sequences, fibo-, tribo- etc. all starting w. 1,1,2 etc, the NW to SE diagonals can be extended by computation. The above is diagonal 7. See A159741 for details.at n=18A159743
