Background A possible origin of this puzzle is found in a dialogue between Socrates and Meno written by the Greek philosopher, Plato, where a square is drawn inside a square such that the blue square is twice the area of the yellow square.  In the 2x2 layout colouring the triangles produces a starting pattern which is a one-diamond figure made up of four tiles and there are 24 different possible arrangements.   In a 4x4 layout with a sixteen tile figure, as used in our puzzle, there are 35 basic x (6 x 4 variations) = 840 possible patterns revealed by swapping rows, columns and the four 2x2 quadrants! |
