Grassmann Coordinates

An $(m+1)$-D Subspace $W$ of an $(n+1)$-D Vector Space $V$ can be specified by an $(m+1)\times(n+1)$ Matrix whose rows are the coordinates of a Basis of $W$. The set of all ${n+1\choose m+1}$ $(m+1)\times(m+1)$ Minors of this Matrix are then called the Grassmann coordinates of $w$ (where ${a\choose b}$ is a Binomial Coefficient).
