We show that coresets do not exist for the problem of 2-slabs in R 3 , thus demonstrating that the natural approach for solving approximately this problem efficiently is infeasible. On the positive side, for a point set P in R 3 , we describe a near linear time algorithm for computing a (1 + e)-approximation to the minimum width 2-slab cover of P. This is a first step in providing an efficient approximation algorithm for the problem of covering a point set with k-slabs.
