(algebra, group theory) The set that results from applying a group's binary operation with a given fixed element of the group on each element of a given subgroup.

Usage notes

Mathematically, given a group \(G\) with binary operation \(\circ\), element \(g\in G\) and subgroup \(H\subseteq G\), the set \(\left \{ g\circ h: h\in H \right \}\), which also defines the left coset if \(G\) is not assumed to be abelian.
