... many of the packings displayed in [2] show, by rotating by half a right-angle certain squares from the trivial method of packing squares, we may be able to pack one extrasquare, or even many ... construction that it is possible to have a packing so efficient that the wastedarea is O(n7/11) for large n. By way of contrast, the ‘trivial’ packing of unit squares gives a wasted area of (n + δ)2− ... 5References.[1] P. Erd˝os and R. L. Graham, “On packing squares with equal squares , J.
