If you have hitherto conceal'd this sight,
Let it be tenable in your silence still.
And whatsoever else shall hap to-night,
Give it an understanding, but no tongue.
This is an arrangement puzzle. There are eight pieces, representing all of the distinct ways that one, two, and three holes can be placed in four spots on a 4x1 rectangle.
You will lay four of these down horizontally next to each other to form a square. You will then lay the remaining four vertically on top of that square. You may rotate or flip any of the pieces before putting them down. The aim of the puzzle is to cover up all of the holes on the bottom layer with the pieces on the top layer. In other words, none of the holes in the top pieces should overlap with the holes in the bottom pieces.
Example: The left picture shows the bottom layer consisting of four pieces placed horizontally. The middle picture shows the remaining four pieces placed vertically. The vertical pieces are then placed on top of the horizontal pieces; the right picture shows the result. In this case, three of the bottom holes are still uncovered. This is not a successful arrangement.
Please present or somehow describe a successful arrangement. There may be many solutions.
