You can link to specific answer, for example, as https://math.stackexchange.com/a/955298 or https://math.stackexchange.com/q/955285#955298 or https://math.stackexchange.com/questions/955285/2-connected-‌​graphs-with-a-line-g‌​raph-containing-no-h‌​amilton-cycle/955298‌​#955298. (The link in your post is to the list of all answers ordered by score - depending in voting, it might change which answer is shown at the top.
