Self-orthogonal codes constructed from orbit matrices of symmetric block designs

Harada and Tonchev presented a construction of self-orthogonal codes from orbit matrices of symmetric designs with fixed-point-free automorphisms. In this talk we describe a construction of self-orthogonal codes from orbit matrices of symmetric designs admitting certain automorphisms with fixed points (and blocks).
