In this paper, we use the definition of ( ℱ 1 , ℱ 2 )‐chaos introduced recently by Tan and Xiong together with the properties of residual relations as a tool in construction of various kinds of scrambled sets. In particular, we show that a continuous map acting on a compact metric space has an ε ‐scrambled set if and only if it has a distributionally ε ‐scrambled set with respect to a sequence. We also provide an example of a topologically mixing map with positive topological entropy but without DC1 pairs.
