We prove the non-existence of extended perfect codes in H(n,q), where q=3,4 and n>q+2 or both n and q are odd. In particular, we prove the non-existence of non-linear (q+2,qq1,4)q MDS codes when q is odd.

关于不存在扩展1-完美码和MDS码

我们证明了扩展完美码的不存在H(n,q), 在哪里q=3,4n>q+2或者nq都是奇数。特别是,我们证明了非线性的不存在(q+2,qq-1,4)qq为奇数时的 MDS 代码。
