Comment on What are the most mindblowing fact in mathematics?

You’re right. Bad example from my side. But imagine the four small countries being four parts of another donut that encompass a smaller country. Then it would be impossible.

That map is actually still quite similar to the earlier example where all 4 donut hole countries are the same. Once again on the right is the adjacency graph for the countries where I’ve also used a dashed line to show the only difference in adjacency. Image

Oh wow, now I feel dumb. Thanks.

Feeling dumb is just the first step in learning something new

Make purple yellow and one of the reds purple.
