Parallel Magnetized Pentominoes


Here are the 35 pieces packed in a 35x5 rectangle.


I think it's possible to construct 5-fold replicas of all heptominoes. For the pentominoes you can try to make three scaled models 1, 3 and 5 times as wide. Unfortunately this is only possible for the I, X and Z pentomino. The T, U and F pentomino must be turned 90 to get a solution and for the other pentominoes a solution can't be derived at all.


An equivalent set with plastic blocks.
