of the finite group G. Then d(G) ≤ d(G/N)+1. Theorem. [20]. Let the finite, non cyclic group G have a unique minimum normal subgroup M. Then d(G) = max(2, d(G/M)). 2. Generator-critical Groups. Let L be the set of finite groups L with the properties: • L has a unique minimal normal subgroup, M;. • if M is abelian then it has a ...
