\22E6
The ⋦ (Less-Than But Not Equivalent To) symbol is a mathematical operator that combines a standard less-than sign with a negated tilde. In advanced mathematics and asymptotic analysis, it denotes that one value or function is strictly less than another while specifically emphasizing that they are not asymptotically equivalent. You will primarily encounter this symbol in complex academic equations, formal logic proofs, and specialized LaTeX documents rather than everyday typography.
