ON REPEATED-ROOT CONSTACYCLIC CODES OF LENGTH 4ps
Hai Quang Dinh · Asian-European Journal of Mathematics · 2013
For any odd prime p, a classification of all constacyclic codes of length 4ps over 𝔽pm is obtained, which establishes the algebraic structure in term of specified polynomial generators of such codes. Among other results, all self-dual and LCD cyclic and negacylic codes of length 4ps are obtained. As an example, all constacyclic codes of length 36 over 𝔽27 and 𝔽81 are listed.
