Abstract: The Donald-Flanigan conjecture asserts that for any finite group and any field , the group algebra can be deformed to a separable algebra. The minimal unsolved instance, namely the quaternion group over a field of characteristic 2 was considered as a counterexample. We present here a separable deformation of . In a sense, the conjecture for any finite group is open again.
