Note that this implies a $\Diff(B^n)$ action on $A$,
since $\cE\cB_n$ contains a copy of $\Diff(B^n)$.
We will define a strict $A_\infty$ $n$-category $\cC^A$.
+(We enrich in topological spaces, though this could easily be adapted to, say, chain complexes.)
If $X$ is a ball of dimension $k<n$, define $\cC^A(X)$ to be a point.
In other words, the $k$-morphisms are trivial for $k<n$.
If $X$ is an $n$-ball, we define $\cC^A(X)$ via a colimit construction.

% According to the referee, yes it is...
Let $A = \cC(B^n)$, where $B^n$ is the standard $n$-ball.

If we apply the homotopy colimit construction of the next subsection to this example,
we get an instance of Lurie's topological chiral homology construction.
