Euler-Mascheroni Constant: Also known as

The Euler-Mascheroni constant $\gamma$ is also known as Euler's constant.

However, this allows it to be confused with Euler's number, so its use is not endorsed by $\mathsf{Pr} \infty \mathsf{fWiki}$.

It is also sometimes known as Mascheroni's constant.

Some sources denote it by the symbol $\mathrm C$.
