A new Gray map between codes over F2k + uF2k + u2F2k and F2k is defined. It is proved that the Gray image of the linear (1 - u2)-cyclic code over the commutative ring F2k + uF2k + u2F2k of length n is a distance-invariant quasicyclic code of index 22k-1 and the length 2 2kn over F2k.eninfo:eu-repo/semantics/closedAccessCyclic Codes; Gray MapArticle1232772792-s2.0-75749155852Q3
