We introduce and investigate binary (k,k)-designs -- combinatorial structures which are related to binary orthogonal arrays. We derive general linear programming bound and propose as a consequence a universal bound on the minimum possible cardinality of (k,k)-designs for fixed k and length n. Designs which attain our bound are investigated.
