Description
Construction and classification of self-orthogonal and self-dual codes is an active field of research. A code for which all codewords have weight divisible by four is called doubly even. Among self-orthogonal, especially self-dual codes, doubly even codes attract special attention. In this talk, we are dealing with some constructions of doubly even self-orthogonal linear codes from incidence matrices and orbit matrices of quasi-symmetric designs. Quasi-symmetric design meaning that this design has exactly two block intersection numbers. In particular, we consider constructions from quasi-symmetric designs of Blokhuis-Haemers type.
