1# Stone's method: sketch the dissection with unknown sides and let the2# geometry solve them. Each group names the squares it hangs under, left to3# right, so the sketch carries its own topology. The solver scales the4# one-dimensional solution to whole numbers.5.view both6title Order 9 solved from a sketch78rectangle ? x ?9(a b)10(c d) under b11(e f) under a12(g h) under f c13(i) under h d
