I had a sitdown in the sofa today with my seven year old boy talking about 6174 and how all those numbers end up there, as well as three digits with 495. I wrote a simple python sript that we could use to go through a lot of numbers to show this. We also talked about how many steps needed to reach those constants. Then we talked about if there were eight steps for any number and we improved the script further, but found none. Goodl talk and sofa-time ;-)
