Resumen de Iterated sums of the cubes of the digits of a natural number

Sergio Falcón Santana

• The sequence of the iterated sums of the cubes of the digits of a natural number can either collapse to a fixed number or enter into a loop formed by a finite subsequence of natural numbers. The aim of this paper is to describe the classes of sequences obtained this way, with the help of a system for mathematical computation.
