摘要：

We prove that Milnor's <(mu)over bar>-invariants are additive under the connected sum operation for links, and establish some corollaries of this result. The appendix describes a technique for finding presentations of nilpotent quotients of groups, and a lemma helpful for locating gropes in the complement of surfaces in four-space.
