The Coated Burr can physically be assembled in 4 ways. But only one of those 4 ways will leave the IPP18 logo intact. That is also the most complex solution (level 5) while the others are simpler. Here is a step by step solution for the one way which gets the IPP18 symbol assembled right:
Step 1: assemble the IPP18 piece and its coat piece.
Step2: add the piece with the one cube cutout and slide the IPP18 piece all the way up.
Step 3: add the only symmetrical coat piece.
Step 4: add the last remaining internal piece (the one with the jvk logo)
Step 5: add the last coat
Step 6: slide all pieces in place (in the order indicated by the arrows)
