Fusion systems over a Sylow p-subgroup of G 2 (p) G2(p)

For S a Sylow p-subgroup of the group G2 (p) for p odd, up to isomorphism of fusion systems, we determine all saturated fusion systems F on S with O p (F) = 1. For p≠7, all such fusion systems are realized by finite groups whereas for p=7 there are 29 saturated fusion systems of which 27 are exotic.
