More precisely, we show that a GAG code is contained (up to isomorphism) in a suitable AG code. Next we recall the concept of an N1N2-automorphism group, a subgroup of the automorphism group of a GAG code. With the use of the relation we obtained between these two classes of codes, we show that the N1N2-automorphism group is a subgroup of the automorphism group of an AG code.en10.2478/auom-2023-0040info:eu-repo/semantics/closedAccessAlgebraic Geometry CodesGeneralized Algebraic Geometry CodesGeometric Goppa CodesCode AutomorphismsAlgebraic Function FieldsArticle313221228N/AWOS:0010981377000122-s2.0-85176250950Q3
