Suppose we have the following pieces (all edge lengths 1 unit):

3 squares
6 rhombi with a 60-degree corner
6 rhombi with a 30-degree corner

If you're familiar with "pattern blocks", that would be 3 orange pieces, 6 blue pieces, and 6 tan pieces.

They can be fit together to make a dodecagon. How many ways can it be done, not including rotations and reflections?
