Brauer–Suzuki theorem

In mathematics, the Brauer–Suzuki theorem, proved by (Brauer Suzuki), (Suzuki 1962), (Brauer 1964), states that if a finite group has a generalized quaternion Sylow 2-subgroup and no non-trivial normal subgroups of odd order, then the group has a centre of order 2. In particular, such a group cannot be simple. A generalization of the Brauer–Suzuki theorem is given by Glauberman's Z* theorem.
