The Double Union symbol (⋓) is a specialized mathematical operator used in set theory and formal logic to represent a complex union between multiple sets. Visually resembling two overlapping union symbols (∪), it serves as a distinct notation for specific binary relations in advanced math. Outside of mathematical equations, digital creatives occasionally use it in ASCII art or custom kaomoji faces for its uniquely curved, double-layered appearance.

In Programming
In LaTeX, the symbol is generated using `\Cup` or `\doublecup` to format complex set equations. Unicode-aware programming languages like Julia also allow developers to define it as a custom operator for specialized set algorithms.
