The Same Upper Bound for Both: The 2-page and the Rectilinear Crossing Numbers of the n-Cube

We present two main results: a 2-page and a rectilinear drawing of the n-dimensional cube Qn. Both drawings have the same number 1257684n−2n−33(3n2+9+(−1)n+12) of crossings, even though they are given by different constructions. The first improves the current best general 2-page drawing, while the second is the first nontrivial rectilinear drawing of Qn.
