Coprime: Also denoted as
The notation $\perp$ is not universal.

Other notations to indicate the concept of coprimality include:


 * $\gcd \set {a, b} = 1$
 * $\map \gcd {a, b} = 1$
 * $\tuple {a, b} = 1$

However, the first two are unwieldy and the third notation $\tuple {a, b}$ is overused.

Hence the decision by to use $\perp$.
