2-groups with a self-centralizing abelian subgroup of type (4,2)

Zvonimir Janko

Sažetak

In this paper we classify finite 2-groups G which possess a self-centralizing abelian subgroup A of type (4,2). In the difficult case, where A is contained in the Frattini subgroup (G), we describe the structure of the group G in great detail. In the other case, where A (G), there is an open problem.
