Codes constructed from orbit matrices of block designs

In this talk we will describe under which conditions the orbit matrix of a block design under the action of automorphism group generates a self-orthogonal code. The obtained results are the generalization of the construction method of self-orthogonal codes from orbit matrices of block designs under the action of an automorphism group of prime order with no fixed points and blocks, given by Harada and Tonchev.
