In 1943, Hadwiger formulated his celebrated conjecture, connecting the chromatic number $\chi(G)$ of a finite, simple, undirected graph with the cardinality of the largest complete minor, $\eta(G)$. The disjoint union of all finite complete graphs shows that Hadwiger's conjecture fails for infinite, but a slightly weak...
