The big 13x13 square shown in the
illustration can be dissected into some number of square pieces
(cutting along the lines only).
The question is what is the minimum number of such squares?
Apparently, the largest possible number is 169, where all the pieces
are of the same size - exactly one cell.
Another sample of solution can be one square 12x12 plus 25 small
squares 1x1 - it makes 26 perfect squares. This is much more better
than 169 perfect squares, but it's still more than a desired
minimum...
In any case, you MUST use all 169 single squares of the 13x13 grid in
your set of square pieces - no single square or their combination can
be omitted. In other words your set MUST fully cover the 13x13 grid
without gaps or overlapping.
