The remaining piece 2
The following figure shows a puzzle that has been
partially completed and the set of accompaining
pieces that must fit in (you can rotate the pieces
and also flip them over).
One of the pieces is however from another puzzle
and won't fit in the solution. Can you discover
what is the shape of the remaining piece ?
Note:  This is the very same problem presented
previously but this time the same solution
can't be applied. Is there a better way than
actually solve the puzzle to find out which one
of the pieces is from another puzzle ?
