The following table lists all currently known APN polynomials over [math]\displaystyle{ \mathbb{F}_{2^8} }[/math]. The majority of these were obtained by the matrix method described in [1] and appear there for the first time. The table is compiled from Appendix 2 in [1]. The symbol "g" in the table is a primitive element of [math]\displaystyle{ \mathbb{F}_{2^7} }[/math].

Due to the large number of functions, the table is split into several pages:

Source code for Magma which produces a sequence of these functions in the same order as given in the table is available.
