The lower central series (or descending central series) of a group G is the descending series of subgroups
G = G1 ⊵ G2 ⊵ ⋯ ⊵ Gn ⊵ ⋯,
where each Gn + 1 = [Gn, G], the subgroup of G generated by all commutators [x, y] with x in Gn and y in G. Thus, G2 = [G, G] = G(1), the derived subgroup of G; G3 = [[G, G], G], etc. The lower central series is often denoted γn(G) = Gn.
