> Can the diamond of radius 14 be colored using a checkerboard pattern of 1s when the center color isn't 6?
Yes - the counterexample given can be shifted left by 1, making a the center color 1 (more 1s can be inserted completing the checkerboard pattern).
I suspect that the conjecture to which this is a counterexample was imprecisely stated in the blog post, although there could also be a reason that a counterexample with a 6 in the center leads to a general counterexample.
