For this puzzle we use the full set of all polycairos consisting of up to 4 cairos. The name Cairo-4 is chosen in analogy to the puzzle Poly-5 using polyominoes up to order 5. The given set of polycairos has to be placed in the given tray. The photo shows an attempt which was not fully successfull. There are many more trays for the polycairos consisting of 88 elementary pentagons.
