    1. The problem statement, all variables and given/known data

    I can't really imagine how this was approached.

    Let [tex] P_{\alpha0} [/tex] fixed

    [tex] P_{a0}A=\frac{1}{N!}\sum_{\alpha}\epsilon_{\alpha}P_{\alpha0}P_{\alpha}=\frac{1}{N!}\epsilon_{\alpha0}\sum_{\alpha}\epsilon_{\beta}P_{\beta}=\epsilon_{\alpha0}A


    2. Relevant equations

    3. The attempt at a solution

    I can understand that [tex] P_{\alpha0}P_{\alpha} = P_{\beta} [/tex] is a new permutation operator.

    [tex] P_{a0}A=\frac{1}{N!}\sum_{\alpha}\epsilon_{\alpha}P_{\alpha0}P_{\alpha}=\frac{1}{N!}\sum_{\alpha}\epsilon_{\alpha}P_{\beta} [/tex]
