U+2A37 "⨷" Multiplication Sign in Double Circle Unicode Character
Unicode Version 17.0
⨷
U+2A37 "⨷" Multiplication Sign in Double Circle is a mathematical symbol used in advanced notation, typically appearing in algebra, set theory, or abstract algebra to represent a binary operation that is multiplicative but distinguished from the standard multiplication sign by being enclosed within a double circle. It may denote a specialized operation such as a tensor product, a direct product, or a binary operation on a group or ring where the double circle emphasizes a closed or cyclic property. Its design combines the familiar X or cross shape of a multiplication sign with two concentric circular borders, making it visually distinct from similar symbols like the circled asterisk or the circled dot operator.
