**2. The little n-cubes operad**

* See Spivak slide 8, "The first operad"

We illustrate for \\(n=2\\), which gives the 'little squares' operad.

There is just a single object \\(\square\\), which serves only as a placeholder.

The entire content of this operad consists of the morphisms from \\(\square_1,...,\square_n \rightarrow \square\\).

Note: the subscript on \\(\square_i\\) is only for counting purposes. They're all the same object.
