These ${q\times {q}}$ pieces will be presented to you in disorder, result of a (hidden) affine transformation of the plane. And your goal is to recover the image by finding the inverse affine transformation. You have the right to multiple tries in order to do it.

Recall that an affine transformation is a linear transformation followed by a translation. All are operations over ${\mathbb{F}}_{{q}}$.

You may play this game even without understanding the mathematics behind. In this case we suggest you don't go further than than ${q=5}$ otherwise the game risks to be very frustrating.
