Union Above Bar Above Intersection Symbol
⩈ is the “union above bar above intersection” mathematical symbol (Unicode U+2A48).
U+2A48
The symbol ⩈ is a specialized math character used to represent a combined relation involving union and intersection with an additional bar. It’s useful in typography, technical writing, and math notation when you need this specific stacked form. Below you’ll find practical copy options and Unicode details.
Union Above Bar Above Intersection Symbol Meaning
⩈ is named “UNION ABOVE BAR ABOVE INTERSECTION” and has Unicode code point U+2A48. In mathematical typography, it visually combines union and intersection in a stacked layout, with a horizontal bar between/over the parts. Because it’s a distinct Unicode character, it’s best used when you specifically need this exact visual construction rather than approximating it with separate symbols. It commonly appears in set- or logic-like notation where authors want to express a relationship that reads as “union” and “intersection” with an intervening bar, such as in formal definitions, comparison of operations, or custom operator styling.
Common uses
- •Math notation in documents and proofs where a stacked union/intersection operator is required
- •Typesetting definitions that reference a custom combined operator symbol
- •Designing educational material with clear, consistent symbolic notation
- •Creating labeled diagrams or notation legends in STEM writing
- •Programming formula rendering systems that rely on Unicode math characters
Examples
⩈ Union Above Bar Above Intersection
- ⩈Let A ⩈ B denote the union-over-bar-over-intersection operator.
- ⩈In the definition, replace the placeholder with ⩈ to show the combined operation.
- ⩈The expression uses ⩈ to distinguish it from a plain union or intersection.
- ⩈Use ⩈ in the proof where the stacked operator is specified.
- ⩈For the operator list, include ⩈ with its Unicode value.
