U+22D2 "⋒" Double Intersection Unicode Character

U+22D2 "⋒" Double Intersection is a mathematical symbol used primarily in set theory and lattice algebra to denote a binary operation that combines two sets, elements, or logical conditions into a new intersection, often representing a double or iterated intersection operation. It visually resembles two overlapping circles or arcs, distinct from the single intersection symbol (∩), and is typically employed in advanced mathematical texts or formal logic to emphasize a specific structural or notational nuance, such as the meet operation in a lattice or the intersection of two subspaces in geometry.
