Let D=(V(D),A(D)) be a digraph and k be an integer with a62c285c9073fdfeeecf24ada5ebae97" title="Click to view the MathML source">k≥2. A digraph D is k-quasi-transitive, if for any path x0x1…xk of length k, x0 and xk are adjacent. In this paper, we consider the traceability of k-quasi-transitive digraphs with even 47a05bfcaaca9d4d4" title="Click to view the MathML source">k≥4. We prove that a strong k-quasi-transitive digraph D with even 47a05bfcaaca9d4d4" title="Click to view the MathML source">k≥4 and has a Hamiltonian path. Moreover, we show that a strong k-quasi-transitive digraph D such that either k is odd or k=2 or may not contain Hamiltonian paths.
