Budaghyan and Carlet [4] constructed a family of almost perfect nonlinear (APN) hexanomials over a field with r2 elements, and with terms of degrees r + 1, s + 1, rs+ 1, rs+ r, rs+ s, and r + s, where r = 2m and s = 2n with GCD(m,n) = 1. The construction requires a certain technical condition, which was verified empirically in a finite number of examples. Bracken, Tan, and Tan [1] proved the co...
