Abstract Algebra 

For each of the following groups \( G \), determine \( e_5 \) = the number of elements of order 5 and \( s_5 \) = the number of subgroups of order 5. Give an example of each.

\[
\begin{array}{|c|c|c|c|c|}
\hline
G & n_5 & \text{an order 5 element} & s_5 & \text{an order 5 subgroup} \\
\hline
\mathbb{Z}_5 \oplus \mathbb{Z}_5 & & & & \\
\hline
U(25) & & & & \\
\hline
\text{Aut}(\mathbb{Z}_{25}) & & & & \\
\hline
\end{array}
