Letandbe a pair of-graphs (writtenand, respectively, when k=2). An-packing ofis a familyof pairwise edge-disjoint copies ofin. Letdenote the maximum sizeof an-packingof. Already in the case of graphs (k=2), Dor and Tarsi proved that computingis NP-hard for every fixed graphhaving a component with three or more edges. On the other hand, Rödl et al. (see primarily [V. Rödl et al. (2007),J. Combin. Theory Ser. B, 97, pp. 245--268]) proved that, for any fixed-graph, the parametercan be approximated within an error ofin time polynomial in. In particular, a foundational result of Haxell and Rödl [P. Haxell and V. Rödl (2001),Combinatorica, 21, pp. 13--38] for graphs () constructs, for every fixed graphand for every given graph, an-packingof sizein time polynomial in. In this paper, we extend the result of Haxell and Rödl to k=3. In particular, for a fixed 3-graph, we establish an algorithm which, for alland for every given 3-graph, constructs an-packingofof sizein time polynomial in. Our approach is based on that of Haxell and Rödl, and uses hypergraph regularity tools of them and the author from earlier papers, together with some details proven here.
