Abstract
We introduce the notion of the metabelian rank of a group and study non-Abelian groups of finite metabelian rank. We prove the following result: If \(G \) is the extension of a locally finite group by a locally nilpotent-by-finite group and the metabelian rank of \(G \) is finite then the special rank of \(G \) is finite too.
