Thank you, exactly the kind of concise treatment I was looking for

I hope my homework tonight is about the Four Color Theory, given its been the last three videos!

I like reading Doron Zeilberger’s take on all of this.

You said that this theorem can be easily proved for 5 colors. Would you give me a reference about it ? I mean how we can understand that 5 colors for every kind of maps are enough?

But can we still check the 1936 cases ourselves as humans?
