In the present article a new type of algebraic structures named as left doubledisplacement semigroup (LDD-semigroup). The structure is enhanced toward its leftdouble displacement group (LDD-group) and discovered some useful results about thesestructures. The name of the notion is due to double displacement reactions in chemistrybecause they have same pattern of elements arrangement.
