Write a question about the following article: The Giants traveled to San Francisco for a rematch of last season's NFC Championship game, in which the Giants won in overtime to advance to Super Bowl XLVI. The San Francisco 49ers were looking to avenge their playoff loss against the Giants, and had just come off back-to-back landslide victories against the Jets and Bills. However, the Giants defense allowed only one field goal and the Giants ultimately won the game 26-3, sending the 49ers to their first and only home loss of the season. With the win, the Giants improved to 4-2. Also, with the Eagles' loss to the Lions earlier in the day, the Giants gained sole possession of first place in the NFC East.
How many points did the Giants win by?
