This property makes sense for infinite groups. For finite groups, it is always true

Definition
A group of finite chief length is a group satisfying the following equivalent conditions:
- It possesses a chief series of finite length, i.e., a normal series of finite length that cannot be further refined.
- It satisfies the ascending chain condition on normal subgroups as well as the descending chain condition on normal subgroups.
