This group action is transitive, so that P (K) is a homogeneous space for the group, often written PGL2(K) to emphasise the projective nature of these transformations. Transitivity says that there exists a homography that will transform any point Q to any other point R. The point at infinity on P (K) is therefore an artifact of choice of coordinates: homogeneous coordinates marvin california instagram
