 OFFSET 0,1 COMMENTS 13 is the smallest number that does not belong to a cycle with elements <= 260000. Further numbers that do not belong to a cycle with elements <= 260000 and do not occur in the trajectory of a smaller number are 15, 32, 45, 59, 72, 76, 81, 85, 95, ... . Conjecture: Sequence is not periodic. LINKS EXAMPLE a(1) = A132948(13) = 20; a(2) = A132948(20) = 35. CROSSREFS Cf. A132948, A132949, A132947.
