Description
here's Stewart Coffin's challenge of this puzzle:
An interesting puzzle is suggested by joining 1 x 2 x 2 blocks in pairs all possible ways. The resulting 10 pieces are shown in Fig. 60. They can be assembled into a 4 x 4 x 5 solid, and there are said to be 25 solutions. Now eliminate the two pieces that are themselves rectangular, and see if the remaining eight (shaded) will assemble into a 4 x 4 x 4 cube. After you have become convinced that they will not, find a set that will by duplicating one piece and eliminating one piece, and note the interesting pattern of symmetry in the solution.
