Query: A finiteness property for preperiodic points of Chebyshev polynomials   Let K be a number field with algebraic closure K-bar, let S be a finite set
of places of K containing the archimedean places, and let f be a Chebyshev
polynomial. We prove that if a in K-bar is not preperiodic, then there are only
finitely many preperiodic points b in K-bar which are S-integral with respect
to a.
