 A good way to check if something similar to the above is an element of a symmetric group is pay attention to the second row. Make sure that it only contains the elements of the set you care about (ex: $\mathbb{Z}_3$) and that there are no repeats.
 
 Let's look at an example of composing two elements from this symmetric group.

 The main thing to remember here is that you must compose from right to left.
 
 $0 \rightarrow 0$ and then $0 \rightarrow 1$, so ultimately $0 \rightarrow 1$.
