Abstract: The representation of mathematical fields can be accomplished by binary rows (or columns) of a binary triangular matrix as the Hamming’s matrices, but this representation don’t show the basic product properties of the fields, that is the nonzero elements of the fields forms a cyclic multiplicative group. In this paper we show that the elements of the fields GF(2n ), and their subgroups, can represent as square matrices by m – sequences, which satisfies the product properties as a cyclic group.
Keywords: Galois fields, m-sequences, cyclic groups, Orthogonal sequences.
