Reed-Muller codes and permutation decoding

We show that the first- and second-order Reed-Muller codes, R(1,m) and R(2,m), can be used for permutation decoding by finding, within the translation group, (m−1)- and (m+1)-PD-sets for R(1,m) for m≥5,6, respectively, and (m−3)-PD-sets for R(2,m) for m≥8. We extend the results of Seneviratne [P. Seneviratne, Partial permutation decoding for the first-order Reed-Muller codes, Discrete Math., 309 (2009), 1967-1970].
