摘要
We describe finite soluble nonnilpotent groups in which every minimal nonnilpotent subgroup is abnormal. We also show that if G is a nonsoluble finite group in which every minimal nonnilpotent subgroup is abnormal, then G is quasisimple and Z(G) is cyclic of order vertical bar Z(G)vertical bar is an element of {1, 2, 3, 4}.
