Lucky Seven is a puzzle ring, woven follow
Bram Cohen's recipe. This particular ring has a wire-style weave, i.e. using constant-diameter wires. The ring has 180-degrees rotation symmetry. This introduced an additional challenge in identifying the rings, as there are three identical twin rings that are not interchangeable in the puzzle solution.
