Do you really mean any involutive linear map? Should the map be also isometric? Is an identity map a reflection? [[User:Boris Tsirelson|Boris Tsirelson]] 17:29, 18 July 2009 (UTC)

: Boris is right. There is also rotation about π. And it should not be restricted to linear spaces since it is a geometric term. I'll give it a try. [[User:Peter Schmitt|Peter Schmitt]] 19:25, 18 July 2009 (UTC)
