Derrick Schneider uses the four trijogs to make his puzzle Square Dance. fit the four pieces into either a 7x9 or 8x8 rectangle. Both solutions are unique. The puzzle was a prize-winner in the Nob Yoshigahara Puzzle Design competition. George Sicherman has enumerated polyjogs.http://www.recmath.org/PolyCur/polyjogs/ The 17 tetrajogs are easy to place into Burr Tools, and they can fit into a 20x20 square. A 19x20 rectangle looks very doable, but Burr Tools wants a few hundred thousand years for that analysis. Can anyone place the 17 tetrajogs into a 19x20 rectangle by hand? --Ed
