Characterizations of skew Hadamard matrices in terms of tournaments are well-known. For n≡2(mod4) , we give a characterization of (−1, 1)-matrices of skew type of order n where their determinants reach Ehlich–Wojtas’ bound in terms of tournaments.application/pdf11engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/TournamentsMaximal determinantsSkew (−1, 1)-matricesinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1007/978-3-319-17729-8_1
