Group action: Notable properties of actions, Orbits and stabilizers & Examples

In mathematics, an action of a group G {\displaystyle G} on a set S {\displaystyle S} is, loosely speaking, an operation that takes an element of G {\displaystyle G} and an element of S {\displaystyle S} and produces another element of S . {\displaystyle S.} More formally, it is a group homomorphism from G {\displaystyle G} to the automorphism group of S…
