14 sticks
I was cleaning up my attic recently and found a set of at least 14 sticks which a curious Italian sold me some years ago. Trying hard to figure out why I bought it from him, I realized that the set has the incredible property that there are no three sticks that can form a triangle. If the set has two sticks of length 1, which are the smallest, what is the least possible length of the 14th stick?
