U+29DE "⧞" Infinity Negated with Vertical Bar Unicode Character

U+29DE "⧞" Infinity Negated with Vertical Bar is a mathematical symbol that represents the concept of infinity crossed out or negated, specifically by a vertical bar running through the center of the standard infinity sign. This glyph is typically used in formal logic, set theory, or advanced mathematics to denote that something is not infinite, or to indicate a termination or limit that is not unbounded. It belongs to the Miscellaneous Mathematical Symbols-B block of Unicode, and its design clearly modifies the familiar lemniscate to express negation through the addition of the vertical line.
