Abstract

Let qq be a prime power. This paper provides a new class of linear codes that arises from the action of the alternating group on Fq[x1,,xm]\mathbb F_q[x_1,\dots,x_m] combined with the ideas in (M. Datta and T. Johnsen, 2022). Compared with Generalized Reed-Muller codes with similar parameters, our codes have the same asymptotic relative distance but a better rate. Our results follow from combinations of Galois theoretical methods with Weil-type bounds for the number of points of hypersurfaces over finite fields.
