The authors introduce a new class of valid inequalities for the polytope of the symmetric travelling salesman problem. They also give complete characterizations of the polytope for 6 and 8 cities. For the latter case, the new inequalities are needed. These results are related to work of R.Z. Norman in the 1950’s.
