Sep 12, 2019 at 3:02 comment added Steven Stadnicki Thank you - the comment is very helpful! Note that just like in the Hopf case, you'll likely need to use two copies of $\mathbb{R}^1$ for each circle, so you may want to talk about six copies of $\mathbb{R}^1$, not three...

Sep 11, 2019 at 21:19 comment added user34104 @StevenStadnicki Thanks! A comment is added in the end, which explains what we mean by $R^1$ lines forming a Hopf link. The question is then about an analogous version for Borromean ring.

Sep 11, 2019 at 20:47 comment added Steven Stadnicki I'm maybe missing something, but there are no obstructions that would limit three mutually nonintersecting, mutually non-parallel $\mathbb{R}^1$ lines from winding up in any configuration whatsoever, so there's no way of distinguishing 'linked' from 'unlinked' lines in a way that would be invariant even under linear transformations.
