Path-sequential labellings of cycles. (English) Zbl 0870.05063

Summary: We investigate labelling the vertices of the cycle of length \(n\) with the integers \(0,\dots, n-1\) in such a way that the \(n\) sums of \(k\) adjacent integers are sequential. We show that this is impossible for both \(n\) and \(k\) even, possible for \(n\) even and \(k\) odd, and that it is possible for many cases where \(n\) is odd. We conjecture that it is always possible when \(n\) is odd.
