U+2240 "≀" Wreath Product Unicode Character
Unicode Version 17.0
≀
U+2240 "≀" Wreath Product is a mathematical symbol used primarily in group theory and combinatorics to denote the wreath product operation, which is a specific construction combining two groups that often appears in the study of symmetries, permutation groups, and the structure of iterated products. Visually, the symbol resembles a small circle encircling a central plus sign or a stylized multiplication sign, and it is used like a binary operator in expressions such as A ≀ B. Its inclusion in Unicode ensures that mathematicians and typesetting systems can represent this specialized algebraic concept consistently across digital texts.
