PUZZLING PENTAGONTM ...posed by Donald Knuth This 16-piece lasercut acrylic puzzle has a lengthy pedigree. From a suggestion by Nob. Yoshigahara, the well-known Japanese puzzlemaster, to the posing of 4 very difficult questions by Don, this puzzle was first distributed at an International Puzzle Party. We developed it further, adding many other designs and questions. There's always something else to explore with it. There are 4 triangle sizes each in 4 colors, which can build 4 separate little pentagons or one large one. Their geometry is related by the "golden ratio." Longest side of largest triangle is 2". Handy cloth storage bag and instructions are included. Recommended ages 10 to adult. (Shipping discount) ![]() ![]() ![]() ![]() |
