But the tricky/strange part in this is 1) there are no other holes to fall into and/or 2) there are no loops to fall into.Anonymoushttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-53837969281947895602007-02-07T11:17:00.000-05:002007-02-07T11:17:00.000-05:00I would imagine it is simply because 6174 is the o...I would imagine it is simply because 6174 is the only 4-digit number which, if you take the largest and smallest digit combinations as shown and subtract, yields itself. The operation is sort of a randomized thing, moving all over the map with random numbers, and 6174 just happens to be the only "trap". I would be interested to find out if this indeed is the case. It would be pretty easy to write a program to look at every number less than 10,000 and check this.Abehttps://www.blogger.com/profile/04424868492071587450noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-35958285231153709432007-02-07T07:14:00.000-05:002007-02-07T07:14:00.000-05:00Your final number is 6174!
