Multiple combinatorial block diagrams

Conditions were presented for design of the combinatorial symmetrical block diagrams with $\sigma>1$ different blocks (elements) for any pair of elements (blocks) to each of which the elements of this pair are incident. The multiple block diagrams may be interpreted as an optimal model of the structure of redundantized links between the system components.
