In P G(2, q 2), q a prime power, we study the set T of Baer subplanes that contain a fixed triangle P QR. To construct a linear rank 2–geometry over T , we determine the dihedral groups, their orders and possible extensions that are generated by the involutions of two Baer subplanes of T. If q +1 is an odd prime, the (q +1) 2 Baer subplanes through the(More)
