U+22C4 "⋄" Diamond Operator Unicode Character

U+22C4 "⋄" Diamond Operator is a mathematical symbol representing a binary operation commonly used in abstract algebra, logic, and combinatorics to denote operations like the tensor product, the diamond product in semigroup theory, or a logical connective for "exclusive or" in certain contexts. Its shape is a small, open rhombus, and it is distinct from other diamond-like characters such as the lozenge (U+25CA) used in typographic ornamentation, as the Diamond Operator is specifically classified under mathematical operators for formal notation.
