About the mathematical right white square bracket symbol

This symbol is read as a right white square bracket, or simply a closing white square bracket. It pairs with the left white square bracket (U+27E6) to form a bracket pair that is visually distinct from standard square brackets, with an open interior that resembles an outlined or hollow form.

It is used primarily in mathematical notation, particularly within the AMS (American Mathematical Society) extensions to LaTeX, where it denotes a closed interval or a specific bracketing style in formal logic and set theory. Less commonly, it may appear in specialized typography or markup contexts where its open design is preferred for clarity.
