## Abstract

Let p1 =p2 = .q =1 (mod 4) be primes such that (2 p1 ) = 1 and (2/p2 ) = (p1/p2 ) = (p1/q ) = Put i = √ .1 and d = p1p2q, then the bicyclic biquadratic field k = Q(ã d, i) has an elementary Abelian 2-class group of rank 3. In this paper we determine the nilpotency class, the coclass, the generators and the structure of the non-Abelian Galois group Gal(k(2)2/k) of the second Hilbert 2-class field k(2) 2 of k, we study the 2-class field tower of k, and we study the capitulation problem of the 2-classes of k in its fourteen abelian unramified extensions of relative degrees two and four. © 2016 World Scientific Publishing Company.
