U+2A8F "⪏" Less-than Above Similar Above Greater-Than Unicode Character

Unicode Version 17.0

U+2A8F "⪏" Less-than Above Similar Above Greater-Than is a mathematical symbol used in formal logic and relational algebra to denote a complex ordering or comparison where a "less-than" relation sits above a "similar" relation, which in turn sits above a "greater-than" relation. It visually stacks three relational operators in a vertical arrangement, indicating a compound or nested relationship between two values, often employed in advanced notation for partial orders, equivalence classes, or multi-step comparisons in technical documents and academic papers. This character is part of the Supplemental Mathematical Operators block, designed to provide precise typographic representation for nuanced relational expressions that standard inequality signs cannot convey.
