Icon requests are off topic. Please keep questions related to their use rather than asking what a good icon to represent a certain item/concept would be.
Icons are frequently used for menu options and actions. They often, but not always, show a representation of the action. Icons should be memorable and easily distinguishable from each other. It is not necessary that they accurately represent the action to be performed.
