The ⊲ (Normal Subgroup Of) symbol is a mathematical operator primarily used in abstract algebra and group theory. It visually resembles a hollow, left-pointing triangle and denotes that one mathematical group is a normal subgroup of another. Outside of advanced equations, it occasionally appears in technical typography as a stylized left-pointing directional arrow or bullet point.
