Order of the Fib elements

On the definitions of "below" and "above" in a Fib object the order of Fib elements is established. To each Fib element in the complete Fib object an unique natural number is assigned. If in a Fib object $N$ elements exist, the numbers $1$ to $N$ will be assigned to the Fib elements in the Fib object. Fib elements below a Fib element are assigned to higher values.

If a list element subobject $Obj_U$ has a higher number $U$ as another subobject $Obj_K$ ($U>K$) of the list element, it also contains Fib elements with higher numbers as the Fib elements in $Obj_K$. The root-elements are treated the same way in the order as list elements, with the main-Fib-object as the first subobject after which the sub-root-objects follow in ther succession (in the root-element).

The same applies for any other branch element. The above defined syntax determines the order of the subobjects.

In figure 3 a sample object with the corresponding numbers (next to the elements) for the order of the Fib element is shown.
