## subgroup

subgroup A subset T of a group G on which the dyadic operation ◦ is defined; T contains the identity, e, of G, the inverse x–1 for any x in T, and the quantity x y for any x and y in T. For any group G the set consisting of e alone is a subgroup; so also is the group G itself. All other subgroups are proper subgroups of G.
