Optimal Ternary Codes with Weight $w$ and Distance $2 w - 2$ in $ℓ_{1}$ -Metric

Xin Wei, Tingting Chen, Xiande Zhang

The study of constant-weight codes in $ℓ_{1}$ -metric was motivated by the duplication-correcting problem for data storage in live DNA. It is interesting to determine the maximum s…

Covering Radius of Permutation Groups with Infinity-Norm

Xin Wei, Xiande Zhang

The covering radius of permutation group codes are studied in this paper with $l_{\infty}$ -metric. We determine the covering radius of the $(p, q)$ -type group, which is a direct pro…
