The article explores different types of chaos in sequences and their relationships. It introduces a new version of chaos called DC 2', which has specific properties. The researchers found that distributional chaos in a sequence is equivalent to distributional chaos under certain conditions. They also discovered that distributional chaos in a sequence and w-chaos do not always imply each other. Additionally, they showed that if a function meets the criteria for DC 2', then raising it to any positive integer power will also result in a function that meets the criteria for DC 2'.
