Walsh spectra of all known APN functions over GF(2^8)

The tables below contain the Walsh spectra for all quadratic APN functions of dimension 8 as given in the appendix of "A Matrix Approach for Constructing Quadratic APN Functions". All 8180 functions listed in the appendix have one of the following three Walsh spectra:

• $\{-32^{2380},-16^{20400},0^{16320},16^{23120},32^{3060}\}$ (same as the Gold functions)
• $\{-64^{6},-32^{2240},-16^{20880},0^{15600},16^{23664},32^{2880},64^{10}\}$ (type 1)
• $\{-64^{12},-32^{2100},-16^{21360},0^{14880},16^{24208},32^{2700},64^{20}\}$ (type 2)

There are 12 functions with a Walsh spectrum of type 2 (given in the table below), 487 functions with a Walsh spectrum of type 1, and 7681 functions with a Gold-like Walsh spectrum (not listed below due to space limitations).
