When will this first differ from A159887, the trajectory of 29 under repeated application of the map n -> A102370(n)?
A bound on the sequences starting to differ is when the appearance of 2^135 - 135 here is followed by 2^135 - 5. This is because A102370(2^135 - 135) = 2^136 - 5. - Peter Munn, Jan 12 2024
