Soddy's hexlet

Soddy's Hexlet is a mathematical puzzle invented by British mathematician and economist Frederick Soddy in the 1920s. It is also sometimes called Soddy's Octagon. The puzzle consists of six identical pieces (called hexlets) that fit together in a specific pattern. Each of the hexlets has three cuts and three knobs on its sides. The goal of the puzzle is to fit the pieces together so that the three knobs of each hexlet meet. It might sound simple, but it isn’t easy! To solve the puzzle, you need to use your imagination and problem-solving skills to find the right way to combine the pieces. Once you’ve done that, you’ll have created a little hexagonal shape. Congrats! You’ve just solved Soddy’s Hexlet!
