There are eight friends A, B, C, D, E, F, G and H sitting around a square table in such a way that four of them are sitting at the corners and four at the sides of the table. All of them are facing inside the table but not necessarily in the same order. Four people are sitting between D and F when counted from the right of D who is sitting at the corner. Only one person is sitting between E and F. C is sitting immediate left of F but is not adjacent to E. G is sitting immediate left of A. A and B are sitting opposite to each other. Then how many people are sitting between F and G when counted from the left of F?
