Abstract

Let GG be a 55-group of maximal class and γ2(G)=[G,G]\gamma_2(G) = [G, G] its derived group. Assume that the abelianization G/γ2(G)G/\gamma_2(G) is of type (5,5)(5, 5) and the transfers VH1γ2(G)V_{H_1\to \gamma_2(G)} and VH2γ2(G)V_{H_2\to \gamma_2(G)} are trivial, where H1H_1 and H2H_2 are two maximal normal subgroups of GG. Then GG is completely determined with the isomorphism class groups of maximal class. Moreover the group GG is realizable with some fields kk, which is the normal closure of a pure quintic field.
