Out-arcs pancyclic vertices problems are interesting in graph theory.This paper investigates the out-arcs pancyclic vertices under a few limited conditions for 4-strong tournament.Path-contraction is used to give a sufficient condition for existing three out-arcs pancyclic vertices.Some related conclusions are given in this paper.
