COMMENTS

Thanks to the work of Chai Wah Wu, it is known that all numbers less than 234 have trajectories that end either at a fixed point or in a cycle of length 2. David J. Seal and _Sean Irvine_ have also studied these trajectories. See A230625, A230626, A230627 for the latest information.
For numbers less than 12388, all trajectories either end at a fixed point or in a cycle of length 2.
