# One-dimensional Symmetry Group

A one-dimensional symmetry group is a mathematical group that describes symmetries in one dimension (1D).

A pattern in 1D can be represented as a function f(x) for, say, the color at position x.

The 1D isometries map x to x + a and to ax. Isometries which leave the function unchanged are translations x + a with a such that f(x + a) = f(x) and reflections ax with a such that f(ax) = f(x).

Now, honestly: if a large group of ... demonstrators blocked the entrances to St. Patrick’s Cathedral every Sunday for years, making it impossible for worshipers to get inside the church without someone escorting them through screaming crowds, wouldn’t some judge rule that those protesters could keep protesting, but behind police lines and out of the doorways?
Anna Quindlen (b. 1953)

What makes a regiment of soldiers a more noble object of view than the same mass of mob? Their arms, their dresses, their banners, and the art and artificial symmetry of their position and movements.
George Gordon Noel Byron (1788–1824)
