The closest I could find in Koshy's book is Theorem 16.5 (on page 200),
which states that L(m)|F(n) iff 2m|n with m > 1. I also thought I could dash
out a quick and dirty Mathematica program to explore your observation, but
in between getting sidetracked with the many interesting things in Koshy's
book and the million things I have to do, I just couldn't concentrate on
this problem.
