Abstract: A geometry is defined by the 56-dimensional representation $ \mathfrak{M}$ of a Lie algebra of type $ {E_7}$. Every collineation is shown to be induced by a semisimilarity of $ \mathfrak{M}$, and the image of the automorphism group of $ \mathfrak{M}$ in the collineation group is shown to be simple.
