Corrigendum to 'Construction of extremal self-dual codes over F_2 + uF_2 with an automorphism of odd order' [Finite Fields Appl. 18 (2012) 971-992]

摘要

In the published version, we claim that there is no Lee-extremal self-dual code of length 22 with an automorphism of type 5-(2,22), and there are exactly 106 inequivalent Lee-extremal self-dual codes of length 22 with an automorphism of type 5-(4,2). However, we confirm that in fact there exist 23 inequivalent Lee-extremal self-dual codes of length 22 with an automorphism of type 5-(2,22), and there are exactly 113 inequivalent Lee-extremal self-dual codes of length 22 with an automorphism of type 5-(4,2).
