Nope, that does not help. We choose a smaller one to test our assertions because the smaller problems have a unique property that the larger ones do not.

Hi bobbym

What properties? I noticed that for one there's not much testing. There's only one case. Is that what you meant?

what properties

The art of combinatorics can defined as counting without actually counting. Small problems have one property that larger ones do not, that is we can violate the above principle easily.

Although the previous posted answer is very difficult to derive the question I gave you is well within your capabilities. So, do you have an answer yet?
