How to describe a comparison between three objects?

I am comparing three things, but how could I describe the relative order in a single sentence?

For example, is "A is greater than B greater than C" valid? Or is there a formal way to describe this?

Solution 1:

You can, but you need two clauses for the two different points being made, e.g.:

A is greater than B, which is greater than C. A is greater than B, and both are greater than C. etc.
