{wiki=Category:Group_actions_(mathematics)}
In mathematics, particularly in the field of group theory, a group action is a way in which a group can operate on a mathematical object. More formally, if \\( G \\) is a group and \\( X \\) is a set, a group action of \\( G \\) on \\( X \\) is a function that describes how elements of the group transform elements of the set.
