U+22CB "⋋" Left Semidirect Product Unicode Character

U+22CB "⋋" Left Semidirect Product is a mathematical symbol used primarily in group theory and abstract algebra to denote the left semidirect product operation, where one group acts on another from the left. In this notation, the open side of the symbol faces to the left, distinguishing it from the right semidirect product (U+22CA "⋊"), and it is typically placed between two groups, such as in "G ⋋ H", to indicate that the group on the left is the acting group. This symbol helps concisely represent the structure of a group as a combination of two subgroups, with the action defined by a homomorphism from the left group into the automorphism group of the right group.
