Gardner [''Mathematical Games: Snarks, Boojums, and Other Conjectures Related to the Four-Color-Map Theorem,'' Scientific American, vol. 234 (1976), pp. 126-130], a snark is a nontrivial cubic graph whose edges cannot be properly colored by three colors. The problem of what ''nontrivial'' means is implicitly or explicitly present in most papers on snarks, and is the main motivation of the present paper. Our approach to the discussion is based on the following observation. If G is a snark with a k-edge-cut producing components G(1) and G(2), then either one of G(1) and G(2) is not 3-edge-colorable, or by adding a ''small'' number of vertices to either component one can obtain snarks <(G)over tilde (1)> and <(G)over tilde (2)> whose order does not exceed that of G. The two situations lead to a definition of a L-reduction and k-decomposition of G. Snarks that for m < k do not admit m-reductions, m-decompositions, or both are k-irreducible, k-indecomposable, and k-simple, rAccording to M.
