Suppose we want to cover all the vertices of the n dimensional hypercube {0,1}$^n$  using minimum number of hyperplanes. Observe that this can be easily done using only two hyperplanes: any two hyperplanes containing two opposite (n-1) dimensional faces are sufficient. Moreover, no single hyperplane can cover all the vertices. Now what if we want to cover only a subset of the hypercube? For example, suppose we want to cover all the vertices of {0,1}$^n$ except one vertex, viz. the origin, leaving out the origin as uncovered. One can observe that n hyperplanes are sufficient. But can we do better? The celebrated covering result by Alon and F$\ddot{u}$redi shows that at least n hyperplanes are necessary also. We shall discuss different versions of this covering problem and we shall prove a generalization of Alon and F$\ddot{u}$redi's covering result for any symmetric subset of the hypercube.
