 * Birth of the Magnetic Tower of Hanoi "Trick"

Following a USA museum visit (summer 1984), I sat resting outside the museum, probably waiting for my wife and kids to show up. Staring at a near-by wall, I re-played an imaginative Tower of Hanoi (ToH) puzzle. Realizing that the ToH game elegantly spans base 2, I tried to generalize the puzzle to span base 3, and "stumbled" over the Magnet trick. Back in Israel that summer, I prepared a home version (of the Magnetic Tower of Hanoi – see picture) and had my kids play with it. Meanwhile I struggled with the mathematics. I came close but, after several long evenings, eventually laid the pencil down. No less than twenty-five dormant years have passed, until a casual event triggered the end of a long hibernation period. Still with a pencil, I cracked the puzzle. And, consulting a modern computer, I came to realize its full mathematical elegance.
