Your grandfather would likely enjoy discussing it with you!
- cjauvin 7y agoWow thank you! So I just learned the proper name of this "puzzle", which my father also showed me a long time ago (and for which I used to fill pages and pages of trials even though I knew that it had no solution), and which I tried to render as an "applet toy", a couple of years ago on my blog (see my other comment below).
