{wiki=Extension_of_a_topological_group}
In the context of topology and abstract algebra, an **extension** of a topological group refers to a way of constructing a new topological group from a known one by incorporating additional structure. This often involves creating a new group whose structure represents a combination of an existing group and a simpler group.
