Abstract: 
For a closed PL manifold M, we consider the configuration space F(M,k) 
of ordered k-tuples of distinct  points in M. We show that a suitable 
iterated suspension of F(M,k) is a homotopy invariant of M. The number 
of suspensions we require depends on three parameters: the number of 
points k, the dimension of M and the connectivity of M. Our proof uses 
a mixture of embedding theory and fiberwise algebraic topology.
