Intersection Above Bar Above Union Symbol Meaning
⩉ is the “intersection above bar above union” symbol (Unicode U+2A49). Visually, it places intersection-like and union-like components in a stacked arrangement, with an additional bar structure between/around them. In practice, this symbol is typically found in mathematical expressions where authors want to show a combined or constrained relationship involving intersection and union. Because it’s a niche symbol, it’s most common in specialized textbooks, typeset math, or notation systems that distinguish multiple set-operations graphically.
Common uses
- •Representing a combined set-operations relationship in formal math text
- •Typing specialized logic or set-theory notation in equations
- •Using as a decorative or clarifying marker in technical documentation
- •Including in LaTeX/Unicode-based math content where the exact glyph is required
- •Correctly pasting into design mockups that must match math typography
Examples
⩉ Intersection Above Bar Above Union
- ⩉A ⩉ B denotes a combined intersection/bar/union relationship
- ⩉We analyze ⩉ as part of the set-operation notation in the proof
- ⩉In the diagram, ⩉ marks the constrained combination of two sets
- ⩉The expression uses ⩉ to distinguish this case from a plain union
- ⩉For notation consistency, replace the placeholder with ⩉
