$h$ is identity as soon as $h(\Sigma)\cap \Sigma$ contains at least 5 points
oh right how silly of me to look over that. Thank you so much!

Hi. Thank you very much for your reply. May I clarify a few things? For case 1) why is $h(p_i)=p_{f(p_i)}$ uniquely determined for $i=1,2,3,4$ and how does this suggest $h(p_5)=p_{f(p_5)} $ does not hold generically?
