We provide three techniques for constructing nonlinear zigzag functions from [GF(q)]^n to [GF(q)]^m. Taking use of permutations on [GF(q)]^m, we can construct new zigzag functions from old ones. This leads us to...

Finding good upper bound for the size of m-ary t-symmetric error correcting codes (t-sEC/AUED codes) codes is the main problem in the coding theory of m-ary t-sEC/AUED codes. Based on the method of Lagrange multipli...
