Legendre Symbol: Also known as

The Legendre symbol for fixed prime $p$ is also known as the quadratic character modulo $p$.

However, that term is defined on $\mathsf{Pr} \infty \mathsf{fWiki}$ from this as simply whether an integer $a$ is a quadratic residue of $p$ or not, without assigning the result to an integer variable.

Hence Legendre symbol will be used throughout.
