Here is a 8X8 square containing numbers 1 to 5 repeated four times. Can you divide the square into four similar shaped pieces such that each piece contains only one set of five numbers?

 ------------------------------- 
| 1 |   |   |   |   |   |   | 1 | 
 ------------------------------- 
| 4 | 3 |   |   | 4 |   |   |   | 
 ------------------------------- 
|   |   |   |   | 5 |   |   | 2 | 
 ------------------------------- 
|   |   |   |   | 5 |   |   | 2 | 
 ------------------------------- 
| 3 |   |   | 5 | 5 |   |   |   | 
 ------------------------------- 
|   |   |   | 3 |   |   |   |   | 
 ------------------------------- 
| 4 |   | 2 | 2 |   |   |   |   | 
 ------------------------------- 
| 1 |   |   |   |   | 3 | 4 | 1 | 
 ------------------------------- 

First draw lines between two of the same numbers. They can't go together. Also note that there is no three in the upper right hand corner. The shape will have to be oblong.
