Given a k-uniform hypergraph, the Maximumk -Set Packing problem is to find the maximum disjoint set of edges. We prove that this problem cannot be efficiently approximated to within a factor of \( \Omega {\left( {k/\ln k} \right)} \) unless P = NP. This improves the previous hardness of approximation factor of \( k/2^{{O({\sqrt {\ln k} })}} \) by Trevisan. This result extends to the problem of k-Dimensional-Matching.
