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 A. 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.
