U+2A79 "⩹" Less-than with Circle Inside Unicode Character

U+2A79 "⩹" Less-than with Circle Inside is a mathematical symbol used primarily in formal logic and mathematics to denote a specific relational operation, often representing a strict order combined with a containment or subset-like relationship. The design features the standard less-than sign (<) with a small circle enclosed within its angle, visually merging the concepts of inequality and circular inclusion. It is distinct from similar characters like the less-than with dot or less-than with loop, and its use is typically found in advanced equations or set theory contexts where precise notation is required. The character is part of the Supplemental Mathematical Operators block, which provides specialized symbols not available in basic Unicode.
