The ⋑ symbol, formally known as the Superset With Overbar, is a specialized mathematical operator used in advanced set theory and formal logic. It visually combines the standard superset symbol (⊃) with a straight macron line across the top, often indicating specific variations of superset relationships such as topological closures. While rarely seen outside of academic math proofs, it remains a vital character for accurate digital typesetting in mathematical computing.

In Programming
Primarily used in mathematical markup languages like LaTeX and MathML to render complex set theory formulas, rather than as a functional operator in standard programming languages.
