Subgroup series can simplify the study of a group to the study of simpler subgroups and their relations, and several subgroup series can be invariantly defined and are important invariants of groups. A subgroup series is used in the subgroup method. Subgroup series are a special example of the use of filtrations in abstract algebra.
Sóc Trăng (362,029 people, constituting 30.18% of the province's population and 27.43% of all Khmer in Vietnam), Trà Vinh (318,231 people, constituting 31.53% of the province's population and 24.11% of all Khmer in Vietnam), Kiên Giang (211,282 people, constituting 12.26% of the province's population and 16.01% of all Khmer in Vietnam), An ...
A subgroup H of a group G is ascendant if there is an ascending subgroup series starting from H and ending at G, such that every term in the series is a normal subgroup of its successor. The series may be infinite. If the series is finite, then the subgroup is subnormal. automorphism An automorphism of a group is an isomorphism of the group to ...

Starting in 2003, ' The Most Beloved Vietnam Television Dramas' Voting Contest (Vietnamese: Cuộc thi bình chọn phim truyền hình Việt Nam được yêu thích nhất) is held annually or biennially by VTV Television Magazine to honor Vietnamese television dramas broadcast during the year(s) on two channels VTV1-VTV3.

Then every subnormal subgroup of G is serial. If the chain C is well-ordered and ascending, then H is an ascendant subgroup of G ; if descending, then H is a descendant subgroup of G . If G is a locally finite group , then the set of all serial subgroups of G form a complete sublattice in the lattice of all normal subgroups of G .
Vietnamese (tiếng Việt) is an Austroasiatic language spoken primarily in Vietnam where it is the official language. It belongs to the Vietic subgroup of the Austroasiatic language family. [6] Vietnamese is spoken natively by around 85 million people, [1] several times as many as the rest of the Austroasiatic family combined. [7]
Equivalently, a group G is polycyclic if and only if it admits a subnormal series with cyclic factors, that is a finite set of subgroups, let's say G 0, ..., G n such that G n coincides with G; G 0 is the trivial subgroup; G i is a normal subgroup of G i+1 (for every i between 0 and n - 1) and the quotient group G i+1 / G i is a cyclic group ...
