Forgive me for stating the obvious: Perhaps we can hope for something
less, such as proving 9 is the only composite number in the sequence or
that the sequence is infinite?
Note from sci.math post:
L(n) is the number of points of period n in the golden
mean shift. The number of orbits of length n in the
golden mean shift is given by the n-th term of the
sequence A006206
Sincerely,
Creighton
