Abstract

This paper introduces a class of Hermitian LCD 22-quasi-abelian codes over finite fields and presents a comprehensive enumeration of these codes in which relative minimum weights are small. We show that such codes are asymptotically good over finite fields. Furthermore, we extend our analysis to finite chain rings by characterizing 22-quasi-abelian codes in this setting and proving the existence of asymptotically good Hermitian LCD 22-quasi-abelian codes over finite chain rings as well.
