We prove that two arithmetically significant extensions of a field F coincide if w x and only if the Witt ring WF is a group ring β€«ήšβ€¬rn G . Furthermore, working modulo squares with Galois groups which are 2-groups, we establish a theorem analogous to Hilbert's Theorem 90 and show that an identity li
