Make purple yellow and one of the reds purple.
Comment on What are the most mindblowing fact in mathematics?
Blyfh@lemmy.world 1 year agoYou’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.

…There is no purple though?

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
