Hello,

I´m in need of a "neutral" sign for indicating that two Mathematica expressions are equivalent (in the sense that they have the same value). For this purpose, I recently started using Equilibrium. For example:

expr[[n1,n2]]\[Equilibrium]Part[expr,n1,n2]

Part[expr,n1,n2]\[Equilibrium]Part[Part[expr,n1],n2]

Would anyone like to offer a suggestion for such a sign?
