The ⊶ (Original Of) symbol is a mathematical operator used in set theory and mapping to denote the pre-image of an element under a specific transformation. Visually resembling a small barbell or connected circles, it illustrates the exact starting point of a mapped relationship. While rarely seen outside of advanced mathematics, it provides essential shorthand for logicians and researchers detailing inverse relations.
