We consider the 490 APN functions in dimension 7 constructed by the matrix method [1] We enumerate the functions in the order in which they appear in [1].

All of these 490 functions have one of the 14 values 3610, 3708, 4026, 4034, 4038, 4040, 4042, 4044, 4046, 4048, 4050, 4270, 4704, 8128 as their -rank. The following table lists the indices of the functions having each of the given -rank.
