Could you please provide some program help documentation?

Hello,

I would like to calculate the number of C5-free connected graphs of order $n$ (where $n\le 10$), and also determine the maximum number of edges for each order. I have tried using count, but I am not very familiar with it. I have noticed the program "forbidden-subgraphs.cc", so I believe it should be able to do it.

Thank in advance.
Licheng.

Hi, I've created a branch with a modified count.cc here. You can call it as ./count induced-C5-free and you get this output:

number of (induced) C5-free connected undirected unlabeled graph on n vertices:
1, 1, 1, 2, 6, 20, 105, 726, 7827, 127611, 3166349

I hope this helps for now. I'll think about how to improve the documentation to make it clearer how to add functionality.
