Re: classify

Hi;

What point?


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Re: classify

Yes, you can see that from the graph.

Re: classify

You can also get the answer algebraically without resorting to a graph.
