For the van der Waals interaction among N ground‐state hydrogen atoms, the fundamental significance of the two‐ and three‐body interactions is shown. Some accurate nonadditive three‐body van der Waals interaction constants are reported based on the perturbation wave function obtained by a momentum‐space method. Additive two‐body interaction constants are also given with improved accuracy
