N-ary Square Union Operator Symbol
The ⨆ symbol represents an N-ary square union operator in mathematical notation.
U+2A06
⨆ (U+2A06) is a mathematical operator symbol used in formal typesetting. It appears when authors want to express a union over multiple inputs. This page helps you understand it and copy it into your work.
N-ary Square Union Operator Symbol Meaning
⨆ is the “N-ary square union operator” (Unicode U+2A06). In math contexts, a “union” operator denotes combining sets; the “N-ary” part means it can apply to a collection of terms rather than just two. The “square” styling distinguishes it from other union-looking symbols and matches conventions used in typeset mathematics. You’ll most often encounter ⨆ in documents where formal set operations and operator notation are carefully specified, such as advanced algebra, logic, or lecture notes written with Unicode-capable math fonts.
Common uses
- •Denoting the union of multiple sets or components in mathematical writing
- •Expressing generalized (N-ary) union operations in lecture notes and papers
- •Writing formal set expressions in Unicode-based math content
- •Labeling or describing operator notation in documentation and textbooks
- •Embedding the symbol in worksheets or templates that use consistent Unicode math operators
