Another natural matroid is given by the point sets in general position of an affine space, leading to the concept of an affine design. Accordingly, a t-(n, k, $\\lambda$) affine design of order q is a collection B of (k-1)-dimensional spaces in the affine geometry A = AG(n-1, q) such that each (t-1)-dimensional space in A is contained in exactly $\\lambda$ spaces of B.
