The R2 System can uniquely name each mu-molecule, each mu-atom, and an extremely large variety of subsets of filaments, including most "interesting" subsets of filaments and quite a few "uninteresting" subsets of filaments. It can also name certain Misiurewicz points (although it cannot name them all) and it can name the points at which the external argument has a power of 2 as its denominator (called terminal points).
There are also special naming conventions that allow convenient names to be formed for radicals (a mu-atom plus all of the stuff that "hangs off of it"), cusps, sets of similar features (such as "all mu-atoms on the left side of Seahorse Valley") and few other odds and ends.
See R2 Naming System for cross-references.
