LetFbe a number field with odd class number, and letEbe a quadratic extension ofF. Our main aim is to prove that the 4-rank of the class groupC(E) ofEis equal tom− 1 −rankRE/F, wheremis the number of primes ofFramifying inE,RE/Fisthe generalized Rédei-matrixof local Hilbert symbols with coefficients inand the rank is the rank over. We determine the generalized Rédei-matricesRE/Fexplicitly for biquadratic number fieldsE.
