Proving Norine's Conjecture holds for $n=7$ via SAT solvers

Abstract

We say a red/blue edge-coloring of the $n$-dimensional cube graph, $Q_n$, is antipodal if all pairs of antipodal edges have different colors. Norine conjectured that in such a coloring there must exist a pair of antipodal vertices connected by a monochromatic path. Previous work has proven this conjecture for $n\le 6$. Using SAT solvers we verify that the conjecture holds for $n=7$.
