# Pseudo-Polycubes with up to 3 Cubes

### 3-dim Pieces:

Joining the set of pseudo-tricubes with the two pseudo-dicubes and the single cube we get
12 pieces with a total volume of 32. This is a pretty good set for handsolving and it's even easier
to work with this set than with the pseudo-tricubes, because you can save the smaller pieces for
finishing your construction.

The 4x4x2 box is the only possible box, because one piece doesn't fit into the 2x2x8 box, but a lot of other
symmetric constructions can be made.

I tried to solve the following constructions by hand and finished them in less than 5 minutes each.

### 2-dim Pieces:

Adding the three pieces of smaller order to the set of flat pseudo-tricubes allows for
a rectangle and some other symmetric constructions without holes. For 10 pentominoes a 2-fold
replica can be made. Do you know the pentominoes for which the construction failed?
