Abstract In 1973 Bermond, Germa, Heydemann and Sotteau conjectured that if n divides (n k), then the complete k-uniform hypergraph on n vertices has a decomposition into Hamilton Berge cycles. Here a Berge cycle consists of an alternating sequence v 1, e 1, v 2,…, v n, e n of distinct vertices v i and distinct edges e i so that each e i contains v i and v i+ 1. So the divisibility condition is clearly necessary. In this note, we prove that the conjecture holds whenever k≥ 4 and n≥ 30. Our argument is based on the Kruskal–Katona theorem. The case when k= 3 was already solved by Verrall, building on results of Bermond.
