Ten Plates by Jean Claude Constantin - IPP 28 Prague Exchange by Luc de Smet



This is a rather unique puzzle design by Jean Claude and here’s an excerpt from Brian Pletcher’s blog:


Rochester Puzzle Picnic (Part 5)


“After Jim Strayer's talk, we hung out for a bit and Jeff Aurand started his talk about the Ten Plates puzzle. This is a puzzle designed and made by Jean-Claude Constantin which consists of plates that are to be assembled in the cubic configuration shown here. Each piece consists of five slots, some are long and some are short. A long slot must meet a short slot and visa versa.


Jeff tried to solve this puzzle for a while, but was unable to do so, so he wrote a program to help him do it! His presentation talked about his journey through this process, and was pretty interesting. It culminated in an analysis of all of the possible configurations of this puzzle, based on the 18 distinct pieces that can be created and using sets where all pieces are different. Pretty neat! Rob Stegmann has also analyzed this group puzzles, as you can see on his website here. He refers to this category as Crossed Sticks puzzles.”
