  14. Finding the canonical form of the Markov matrix QT(m) arising from generalized 3x+1 mappings , where either gcd(mi, d )=1 for 0 ≤ i < d, or gcd(mi, d2) = gcd(mi, d) for 0 ≤ i < d and d divides m.
  15. Finding the canonical form of Markov matrix QT(m) arising from George Leigh's Markov chain {Yn(x)}
