We say that H is a BNA -subgroup of G if either H x = H or x ∈ < H, H x > for all x ∈ G. The BNA -subgroups of G are between normal and abnormal subgroups of G. We obtain some new characterizations for finite groups based on the assumption that all cyclic subgroups are BNA -subgroups. 原始语种摘要： Suppose that G is a finite group and H is a subgroup of G.
