Coordinates: Also denoted as
It is usual to use the subscript technique to denote the coordinates where $n$ is large or unspecified:
 * $\tuple {x_1, x_2, \ldots, x_n}$

However, note that some texts (often in the fields of physics and mechanics) prefer to use superscripts:
 * $\tuple {x^1, x^2, \ldots, x^n}$

While this notation is documented here, its use is not endorsed by because:
 * there exists the all too likely subsequent confusion with notation for powers
 * one of the philosophical tenets of is to present a system of notation that is as completely consistent as possible.
