Is there a different, sort of established, notation for the Legendre / Jacobi / Kronecker symbol $\left(\frac{a}{b}\right)$? If yes, where is it used (in which texts)?
I'm asking, because I personally think the notation is absolutely terrible and I really dislike using it in my own notes.
(The notation obviously conflicts with fractions, especially if functions are applied to them, like: $\left(\frac{p-1}{2}\right)!$ or $\mu(\frac{a}{p})$)
