Gang of four patterns usage in automation frameworks

I would like to know which Gang of four design patterns may have important applications when developing an automation framework.

For example Page Object Model (not a Gof pattern btw) is one of the most commonly used design patterns which are incorporated while developing automation frameworks.

In the similar context, I would like to know which of Gof patterns are commonly considered.

Lastly, it could be for any type of automation framework (Key-word, data driven etc).

Thanks.
