For example, let \\(f: \square \rightarrow \square_1,\square_2\\) be the arrangement consisting of the lower left and upper right quarters of the unit square.

The consider the morphism tree consisting of \\(f\\) at the root, with two children that are also \\(f\\).

The composite of this tree (diagram) will be the first iteration of recursively nesting \\(f\\) within itself.

Specifically, it consists of four subsquares, each of length \\(0.25\\), arranged along the diagonal from the lower left to the upper right corners of the unit square.
