Supersolvable group

Definition

Symbol-free definition

A group is said to be supersolvable if it has a normal series (wherein all the members are normal in the whole group) of finite length, starting from the trivial group and ending at the whole group, such that all the successive quotients are cyclic.

Definition with symbols

A group $G$ is said to be supersolvable if there exists a normal series:

$1 = H_0 \le H_1 \le H_2 \le \ldots \le H_n = G$

where each $H_i \triangleleft G$ and further, each $H_{i+1}/H_i$ is cyclic.

Metaproperties

Metaproperty name	Satisfied?	Proof	Statement with symbols
pseudovarietal group property	Yes	supersolvability is pseudovarietal	Supersolvability is closed under taking subgroups, quotients, and finite direct products (see below).
subgroup-closed group property	Yes	supersolvability is subgroup-closed	If $G$ is supersolvable, and $H \le G$ is a subgroup, $H$ is supersolvable.
quotient-closed group property	Yes	supersolvability is quotient-closed	If $G$ is supersolvable, and $H$ is a normal subgroup of $G$, the quotient group $G/H$ is supersolvable.
finite direct product-closed group property	Yes	supersolvability is finite direct product-closed	If $G_1,G_2,\dots,G_n$ are all supersolvable, the external direct product $G_1 \times G_2 \times \dots \times G_n$ is also supersolvable.
