I've already posted two questions on this matter, so I feel I shouldn't post a third. But you could. (I can promise to not answer for a few days to give others a chance). | |

This Q, by contrast, has a clean and elegant geometric A. And on top of that I messed up and failed to exclude a second trivial-ish solution (even though I was aware of it). As I find it annoying when posters change their Q's to disallow legit A's others have put actual effort into I've fixed it in a new Q | |

The generalization of the linked puzzle would be "What is the maximum number M of identical round coins that can be fitted inside a regular N-gon of coins? (without overlap and all lying flat)?" | |
