A Homotopy Equivalence for Partition Pos

We give a homotopy equivalence to explain an S n&1 -module isomorphism which occurs frequently in the homology of subposets of the partition lattice 6 n . The isomorphism in question is necessary for the existence of a lifting to S n of the S n&1 -module involved. It has also been observed in certai
