## 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.
