Proof

[Bryan stel]

Suppose that A be subsets, let F={f|f:A→A} and P={f є F|f is bijective}.Define a relation as follows

R={(f,g) є F X F | Ǝ h є P (f= h^-1 o g composition h (g∙h)) and prove that R is an equivalence relation

P= partition

This sounds like a homework question. People will be happy to provide guidance if you can show you've done some work yourself and what you're stuck on but we don't answer questions for you here
