A 2-chain can interlock with a k-chain
<|reference_start|>A 2-chain can interlock with a k-chain: One of the open problems posed in [3] is: what is the minimal number k such that an open, flexible k-chain can interlock with a flexible 2-chain? In this paper, we establish the assumption behind this problem, that there is indeed some k that achieves interlocking. We prove that a flexible 2-chain can interlock with a flexible, open 16-chain.<|reference_end|>
