# Magic Squares Part 1

How many different 3 by 3 magic squares are possible?

$$\begin{array} {c|c|c} 4 & 3 & 8 \\ \hline 9 & 5 & 1 \\ \hline 2 & 7 & 6 \end{array}$$, $$\begin{array} {c|c|c} 2 & 9 & 4 \\ \hline 7 & 5 & 3 \\ \hline 6 & 1 & 8 \end{array}$$ and $$\begin{array} {c|c|c} 8 & 3 & 4 \\ \hline 1 & 5 & 9 \\ \hline 6 & 7 & 2 \end{array}$$ are the same.
