This term also refers to certain relations that relate f of the quantity a minus x end quantity to f of x.
In Euclidean geometry, the finite groups formed by this type of mapping are equivalent to the finite Coxeter groups.  In computer science, this term refers to the ability of a program to treat itself as data, allowing the program to modify itself. Matrices that perform this operation in two-space often take the form with top row cosine two theta, sine two theta and bottom row sine two theta, negative cosine two theta; those matrices have a determinant of negative one.  This term also refers to certain relations that relate f of the quantity a minus x end quantity to f of x. When this type of transformation is combined with a translation, the result is its glide type. For even functions, this transformation can be found over the y-axis without changing the graph. Name this transformation that finds a mirror image.
