This (common) fixed point or center is called the center of rotation and is usually identified with the origin. The rotation group is a point stabilizer in a broader group of (orientation-preserving) motions. For a particular rotation: The axis of rotation is a line of its fixed points. They exist only in n = 3.

Three commonly used (but different) center points are: the mean center, also known as the centroid or center of gravity; the median center, which is the intersection of the median longitude and median latitude; the geometric median, also known as Weber point, Fermat–Weber point, or point of minimum aggregate travel.
