Abstract: A reformulation and refinement of the $ \overline \mu $-invariants of Milnor are used to give a homotopy classification of $ 4$ component links and suggest a possible general homotopy classification. The main idea is to use the (reduced) group of a link and its "geometric" automorphisms to define the precise indeterminacy of these invariants.
