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 $\mathsf{Pr} \infty \mathsf{fWiki}$ to use $\perp$.
