The ⊌ (Multiset) symbol is a mathematical operator used in set theory to represent a collection where elements can appear more than once. Visually resembling a standard union symbol with a horizontal bar at the base, it helps distinguish multiset notation from regular sets. It primarily appears in advanced mathematics, discrete math documentation, and computer science algorithms.
