    In this paper, we completely classify the finite pp-groups GG such that Φ(G′)G3≤Cp2\Phi(G')G_3\le C_p^2, Φ(G′)G3≤Z(G)\Phi(G')G_3\le Z(G) and G/Φ(G′)G3G/\Phi(G')G_3 is minimal non-abelian. This paper is a part of the classification of finite pp-groups with a minimal non-abelian subgroup of index pp. Together with other four papers, we solve a problem proposed by Y. Berkovich
