Hi MathsIsFun;

That is one tough problem. In opposition to Gasarch my feeling is that it is not 4 colorable.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
