              Abstract
              A topological dynamical system X f is said to be multitransitive if for every n ∈ ℕ the system X n  f × f 2 × … × f n  is transitive We introduce the concept of multitransitivity with respect to a vector and show that multitransitivity can be characterized by the hitting time sets of open sets answering a question proposed by Kwietniak and Oprocha 2012 We also show that multitransitive systems are LiYorke chaotic
