Iterates of functions defined in terms of digital representations of the integers

Thiel, Johann A.University of Illinois at Urbana-Champaign2011

For a fixed base, John H. Conway’s RATS sequences are generated by iterating the following procedure on an initial integer: Reverse the digits of the integer, Add the reversal to the original, Then Sort the resulting digits in increasing order. For example, 334+433=767, which gets sorted into 677. …
