This category contains results about **Normal Series** in the context of **Group Theory**.

Definitions specific to this category can be found in Definitions/Normal Series.

Let $G$ be a group whose identity is $e$.

A **normal series** for $G$ is a sequence of (normal) subgroups of $G$:

- $\set e = G_0 \lhd G_1 \lhd \cdots \lhd G_n = G$

where $G_{i - 1} \lhd G_i$ denotes that $G_{i - 1}$ is a proper normal subgroup of $G_i$.
