New doubly even self-dual codes having minimum weight 20

Research output: Contribution to journalArticlepeer-review

Abstract

In this note, we construct new doubly even self-dual codes having minimum weight 20 for lengths 112, 120 and 128. This implies that there are at least three inequivalent extremal doubly even self-dual codes of length 112.
