U+22E4 "⋤" Square Image of or Not Equal To Unicode Character

U+22E4 "⋤" Square Image of or Not Equal To is a mathematical symbol that combines two distinct relational concepts, representing that one square or matrix is not equal to the image of another under a specific mapping or that it does not hold a square image relation. It is derived from the "square image of" operator, which is often used in advanced algebra or lattice theory to denote a structural correspondence, and the addition of a negation slash or the "not equal" modifier indicates the denial of that relationship. This character appears in the Unicode block for Mathematical Operators and is visually constructed as a small square with a vertical or diagonal negation stroke, making it a precise tool for expressing inequality in abstract mathematical contexts where standard equals or congruent symbols do not apply.
