The number of pancyclic arcs in a $$k$$-strong tournament. (English) Zbl 1081.05041
An arc in a tournament $$T$$ is pancyclic if it lies in directed cycles of all possible lengths, that is, length 3 through length the order of $$T$$. The author obtains significant improvements on bounds for the number of pancyclic arcs in a $$k$$-strong tournament, and the maximum number of pancyclic arcs in a single Hamilton directed cycle of a $$k$$-strong tournament.
