摘要:
Assume G is a finite p-group and i is a fixed positive integer. In this paper, finite p-groups G with vertical bar N-G(H) : H vertical bar = p(i) for all nonnormal subgroups H are classified up to isomorphism. As a corollary, this answers Problem 116(i) proposed by Y. Berkovich in his book "Groups of Prime Power Order Vol. 1" in 2008.
