TITLE: How to draw the 5 dimensional hypercube graph with 56 edge crossings?
QUESTION [7 upvotes]: I'm probably doing something stupid but I can't seem to think of a way to draw $Q_5$ with $cr(Q_5) = 56 $. In this paper the author says drawing a hypercube graph with $\leq56$ edge crossings is easy (look under section 3 topological invariants) Could anyone give me an idea of how to get 56 edge crossings. I always end up getting 60 when I draw it.

REPLY [3 votes]: Here's a cleaner version of the 56 crossing.  The left and right wrap around.
