Is it possible to express the extent to which an alkane has branching (branch count)?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Your question is a bit unclear as to what exactly you are wondering. However, for a simple saturated hydrocarbon what's IUPAC name is given, its base name is given by the largest chain. Knowing this, all branching is indicated by the named substituents that branch off of this main chain.
For example, 2,3,5-trimethylhexane will be a 6-carbon saturated chain with 3 branches. Hopefully this helps answer your question, maybe you can add some clarification?
