A set of Hamilton cycles in the complete graph K_n is called a [double] Dudeney set, if every path of length two lies on exactly one [two] of the cycles. It has been conjectured that there is a Dudeney set for every complete graph. It is known that there exists a Dudeney set of K_n when n is even, but it is still unsettled when n is odd. In this paper, we define a black 1-factor and we show that if there exists a black 1-factor of K_n, we can construct a Dudeney set of K_<n+1>. Furthermore, we extend it to a double Dudeney set.
