Geomagic Squares

A 'normal' 3×3 geomagic square, meaning that piece sizes form the natural progression: 1,2,3,.. It is one of 4,370 normal squares that can be formed showing the same 4×4 square target with inner hole. The rotated and/or reflected variants of each square are not counted in this total. This ubiquity of solutions is in striking contrast to the two only squares to be found when the nine pieces are all decominoes (previous exhibit).
