Interpret connection sums and symmetry
The network shows football teams and their fixtures. Each line is one fixture between the two teams
Use this vertex order for both the rows and the columns of \(M\): Blues, Hawks, Rovers, Tigers. Rows name the starting vertex and columns name the ending vertex
\[M = \begin{bmatrix} 0 & 1 & 1 & 0 \\ 1 & 0 & 1 & 0 \\ 1 & 1 & 0 & 1 \\ 0 & 0 & 1 & 0 \end{bmatrix}\]
