Definition: "Coset" is a mathematical term used in group theory to denote an element of a group. In group theory, a "coset" is defined as the result of multiplying a given element by an element from another group. The operation of coset multiplication is often denoted with a symbol like ⊗ or
.
For example, consider two groups G and H. Let G be a group and let H be a subgroup of G. We can define the coset space (G/H
