Edge Decompositions of Colored GraphsLet . be a class of directed loopless graphs whose edges have been colored with c colors. By Δ. (λ. ,…, λ.) we denote the digraph with v vertices any two of which are joined by λ. edges (in both directions) of color i.

Ovals from the Point of View of Coding Theorynts no three of which are collinear. We split the discussion into three cases: Case 1 is that of a projective plane of even order congruent to 2 modulo 4. Case 2 is that of a projective plane of even order congruent to 0 modulo 4. Case 3 is that of a projective plane of odd order.
