Unicode Version 17.0
⊔
U+2294 "⊔" Square Cup is a mathematical symbol used primarily in lattice theory and order theory to represent the join or supremum of two elements, effectively denoting the least upper bound in a partially ordered set. It is the dual counterpart to the square cap symbol (U+2293) which represents the meet or greatest lower bound. In computing and formal logic, it can also appear in notations for disjoint union or as a binary operator in certain algebraic structures, and its shape resembles an uppercase "U" with a flat top and sharp corners.
