**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.
