U+21DB "⇛" Rightwards Triple Arrow Unicode Character
Unicode Version 17.0
⇛
U+21DB "⇛" Rightwards Triple Arrow is a typographic symbol primarily used in mathematics, logic, and computer science to denote a stronger form of implication, mapping, or transformation, often representing a logical consequence or a multi step functional relationship that is more emphatic than a single arrow. It appears in contexts such as formal proofs, notation for strict implication in modal logic, or as a delimiter in certain programming languages and mathematical diagrams to indicate a chaining or extended direction. While visually distinct due to its three parallel shafts, it remains less common than the single arrow counterpart and is not a standard keyboard character.
