Double Square Union Symbol
⩏ Double Square Union is a math symbol for notating a union-like relation with a double-square shape.
U+2A4F
The ⩏ symbol is called the Double Square Union. It’s primarily used in mathematical or technical contexts where a union-style operator needs a specific visual form. Below you’ll find the Unicode details and practical ways to copy it.
Double Square Union Symbol Meaning
⩏ is the “Double Square Union” symbol (Unicode name: DOUBLE SQUARE UNION, code point U+2A4F). As a Math-category character, it is typically used as a specialized operator-like glyph in formulas, set notation, or structured relationships where a union concept is suggested but the appearance differs from more common union symbols. Because it is a distinct Unicode character, it can be helpful when you need an exact glyph for consistency across documents, typesetting systems, or when matching a reference equation that uses this specific operator.
Common uses
- •Writing or editing mathematical expressions that require the exact U+2A4F glyph
- •Labeling operations in lecture notes or textbooks using a distinct union-like symbol
- •Creating consistent symbols in technical documents and equation worksheets
- •Designing math-focused UI text (e.g., notation palettes or formula builders)
- •Using in code or markup where precise Unicode characters must be preserved
Examples
⩏ Double Square Union symbol
- ⩏Let A ⩏ B represent the combined structure.
- ⩏In our notation, ⩏ is used for a double-square union.
- ⩏The expression uses ⩏ to show an operator relationship.
- ⩏Replace the placeholder operator with ⩏ in the formula.
- ⩏Consistency check: the symbol in the source is ⩏ (U+2A4F).
