In this paper, we establish a lower bound on the total number of inequivalent APN functions finite field with 2 m elements, where is even. We obtain result by proving that introduced Pott and second author [22] , which depend three parameters k s α are pairwise for distinct choices . Moreover, determine automorphism group these functions.
