Radix was the exchange puzzle of its designer Akio Yamamoto at IPP25 in Finland, 2005.
The goal of this puzzle is to take the three pieces apart, and then put them back together again.
This IPP25 version is about 10% larger than my commercially available copy (61 mm vs. 54 mm high).
This IPP25 version has the text "IPP25 in FINLAND" engraved on one of its pieces (see picture 1), and "2005" engraven on an other piece (see drawing in picture 3).
The puzzle comes in its original packing box, with special IPP25 sheet showing the assembled and disassembled puzzle (see picture 3, this is not a solution sheet).
