U+29F4 "⧴" Rule-Delayed Unicode Character
Unicode Version 17.0
⧴
U+29F4 "⧴" Rule-Delayed is a mathematical symbol representing a relation in which a rule or operation is applied after a delay, often used in formal logic, computer science, or process algebra to denote that a transformation occurs at a later time step or under deferred conditions. It belongs to the Supplemental Mathematical Operators block and is visually composed of two horizontal lines with a vertical line crossing through them, indicating a sequential or timed dependency between operands. This character is distinct from similar operators like the regular "rule" arrow (usually drawn as a single line) by explicitly marking the postponement of the action it governs.
