The saturated fusion systems on a Sylow 2-subgroup of ${\Omega}^+_8 (2)$

Abstract

We consider saturated fusion systems $\mathcal F$ on a Sylow $2$-subgroup of $\Omega^+_8(2)$ with $O_2(\mathcal F) = 1$. Examples for this are the $2$-fusion systems of $\Omega^+_8(2)$, $\Omega^+_8(2):3$, $P\Omega^+_8(3)$ and $P\Omega^+_8(3):3$
