First, there are some definitions:

A molecule is a graph, but each side can be multi-plicated.

An atom is a vertex. Atoms are distinguished by its degrees.

A bond is a side, but there is a double bond, triple bond, and so on.

Ataishirube is a degree of an atom. n-ple bond is counted n times.

A molecule is alkanic is that the molecules doesn't have any multiple bonds or loops.

Here is my function:

OC(a_1, a_2, a_3, ... ,a_n) is a number of the molecules. Every single molecule has a_n n-degree atoms for every n.
