e/Product of group subsets

Information
has gloss	eng: In mathematics, one can define a product of group subsets in a natural way. If S and T are subsets of a group G then their product is the subset of G defined by :ST = \st : s \in S \mbox and } t\in T\} Note that S and T need not be subgroups. The associativity of this product follows from that of the group product. The product of group subsets therefore defines a natural monoid structure on the power set of G.
