Math : Infinite-order Groups

An infinite-order group is simply a group that has an infinite number of elements. (Keep in mind that there are different types of infinite.) Here are a few examples:

The set of all integers under the composition of addition.

The set of all displacements (translations) in a common direction with the composition of consecutive displacement. The result of this transformation can be seen in patterns - imagine an infinite plane of wallpaper. These infinite repetitions are also known as tesselations.

The set of all rotations about a point under composition of consecutive rotation. There are infinite symmetry axes in this case (think of a sphere).
