In this paper the authors show the relation between the definitions of Li-Yorke chaos and distributionalchaos in discrete dynamical systems. In particular, after listing the main definitions andreviewing the known results, the authors prove that:• a discrete dynamical system is chaotic in the sense of Martelli and Wiggins when it exhibitstransitive distributional chaos;• a discrete dynamical system is distributively chaotic in a sequence when it is chaotic in thestrong sense of Li-Yorke.Finally, the authors prove a sufficient condition for the dynamical system to be chaotic in thestrong sense of Li-Yorke.
