Place 20 digits from 0 to 9 in the cells of a 5 x 4 rectangular grid such that each row, from left to right, and each column, from top to bottom, is a perfect square. The nine square numbers may or may not be different from each other.
Note: Since there are more than 10 cells, there would be an obvious repetition of digits.
