The ⊳ (Contains As Normal Subgroup) symbol is a mathematical operator primarily used in abstract algebra and group theory. It typically denotes that a larger group contains a smaller one as a normal subgroup, mirroring the ⊲ relation written the other way round. Outside of advanced mathematics, this hollow right-pointing triangle occasionally appears in technical typography as a stylized bullet point, logical indicator, or lightweight play button.
