The Grassmannian is the set of k dimensional subspace of an n dimensional vector space. This set naturally parametrizes isomorphism classes of frames. We will present several results which exploit this fact. In particular, we will use the Plucker embedding of the Grassmannian to identify a class of frames which is optimal for the maximal number of erasures.
