    xkcd’s cartoon depicting a tree of Collatz Conjecture.

    According to this :-

    Consider the following operation on an arbitrary positive integer:

    * If the number is even, divide it by two.
    * If the number is odd, triple it and add one.

    The Collatz conjecture is: This process will eventually reach the number 1, regardless of which positive integer is chosen initially.

    A 2 3 factor tree ??? Bottom up the values keep on doubling and when a branch arrives the value at the node is divided by 3. Some diagrammatic variant of 2,3 trees?
