[seqfan] Divisibilty sequences

[Richard Guy]

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)
