We examine the properties of self-dual skew G-codes and in particular we show that the dual, under any duality, of an additive skew G-code is also an additive skew G-code. Additionally, we propose a matrix construction for additive skew G-codes and use it to construct several examples of extremal self-dual additive skew G-codes over the finite field F4. Such codes have a strong connection to quantum error correcting codes.eninfo:eu-repo/semantics/restrictedAccessAdditive codesSelf-dual codesSkew codesQuantum noiseAdditive codeExtremalFinite fieldsG codesmatrixPropertyQuantum error correcting codesSelf-dualSelf-dual codesSkew codeArticle343423442Q4WOS:0006508257000022-s2.0-85105893759Q1
