Maximum distance separable (MDS) codes are optimal in the sense that the minimum distance cannot be improved for a given length and code size. Twisted Reed–Solomon codes come from Reed–Solomon codes by adding a monomial. In this paper, we give a necessary and sufficient condition that twisted Reed–Solomon codes are MDS (near-MDS). Moreover, we prove that a lot of MDS codes, which are constructed via twisted Reed–Solomon codes, are not equivalent to Reed–Solomon codes.
