The solution is as follows. Place the rectangle face down and upside down
as shown in the diagram on the left. Now fold up the right half so that 5
goes on 2, 6 on 3, 4 on 1 and 7 on 8. Fold the bottom half up so that 4
goes on 5 and 7 on 6. Then tuck 4 and 5 together in between 6 and 3.
Finally fold 1 and 2 beneath, and turn the whole square packet over to see
number 1 on its top. |
