## Abstract The __square__ __G__^2^ of a graph __G__ is the graph with the same vertex set __G__ and with two vertices adjacent if their distance in __G__ is at most 2. Thomassen showed that every planar graph __G__ with maximum degree Δ(__G__) = 3 satisfies χ(__G__^2^) ≤ 7. Kostochka and Woodall c
