robinhouston on Nostr: My version of a very nice, rather difficult, dissection puzzle – of unknown origin ...
My version of a very nice, rather difficult, dissection puzzle – of unknown origin – that has been circulating for many years, but of which I learnt only recently.
(Please at least spoiler-tag any hints, clues, guesses, context, speculation, or attempted solutions; and consider DMing them to me rather than posting publicly at all. This is a hard puzzle, and if it's easy to cheat then the temptation will be powerful.)
