U+2A8B "⪋" Less-than Above Double-Line Equal Above Greater-Than Unicode Character

U+2A8B "⪋" Less-than Above Double-Line Equal Above Greater-Than is a mathematical symbol that combines three relational operators in a vertically stacked format, with a less-than sign above a double-line equal sign, which in turn sits above a greater-than sign. Its primary function is to denote that an expression, typically in formal logic or advanced mathematics, can simultaneously satisfy three distinct relational conditions, such as being less than, sometimes equal to, and greater than in separate contexts or comparisons. This symbol is particularly useful for compactly representing composite or ambiguous ordering relationships where a single, simple inequality does not suffice, and it is encoded in the Unicode standard under the Supplemental Mathematical Operators block.
