I don't seem able to sell these to anyone. Here's a small sample for inclusion (please check! and mention that they're div seqs). R. Some formulas are A004187 = $\frac{1}{3}F_{4n}$, A049682 = $\frac{1}{9}F_{4n}^2$, A003751 = $\frac{125}{81}F_{4n}^4$ A curiosity is A049682(n) - A049682(n-1) = A004187(2n-1)
