Involutory function

In mathematics, an involution, involutory function, or self-inverse function is a function f that is its own inverse, f(f(x)) = x for all x in the domain of f. Equivalently, applying f twice produces the original value. Meer weergeven Any involution is a bijection. The identity map is a trivial example of an involution.
