Abstract
Let h(n,p) be the minimum integer such that every edge-colouring of the complete graph of order n, using exactly h(n,p) colours, produces at least one cycle of order p having all its edges of different colours. In this paper the value of h(n,p) is determinated for n≥p≥3. As a corollary we obtain the equality which was conjectured by Erdös, Simonovits and Sós, 30 years ago [4].
