Intuitively, it seems that radius/length ratio is what's important here.
- mythealias 13y agoYes, length to radius is important factor. Here's a discussion on 7 cylinders touching (using their end) ... http://www.ocf.berkeley.edu/~wwu/riddles/cigarettes.shtml http://www.ocf.berkeley.edu/~wwu/riddles/cigarettes.shtml
- pisarzp 13y agoNo, as this cylinders can be infinitely long if I'm not mistaken
- acchow 13y agoSure, there's no lower bound on the radius/length ratio. But there is an upper bound (think huge radius, short length).
- ColinWright 13y agoYes - currently the best result for coins is 5 mutually touching. Neither beaten, nor proven to be maximal.
