Example of Cycle Decomposition
Consider the permutation given in two-row notation as:
- $\rho = \begin{pmatrix} 1 & 2 & 3 & 4 & 5 & 6 & 7 \\ 5 & 6 & 1 & 7 & 3 & 2 & 4 \end{pmatrix}$
The cycle decomposition for $\rho$ is:
- $\begin{pmatrix} 1 & 5 & 3 \end{pmatrix} \begin{pmatrix} 2 & 6 \end{pmatrix} \begin{pmatrix} 4 & 7 \end{pmatrix}$
