Self-orthogonal codes constructed from orbit matrices of block designs
Loredana Simčić, Dean Crnković · 2012
Harada and Tonchev presented a construction of self-orthogonal codes from orbit matrices of symmetric designs with fixed-point-free automorphisms. We describe a generalization of this result on the construction of self-orthogonal codes from orbit matrices of block designs admitting automorphisms with fixed points and blocks.
