Abstract

We show that (Formula presented.) is finite of order (mi)!(i!)^m−2 and that (Formula presented.) is free abelian of rank m − 1. This is accomplished by showing that the equivariant homotopy groups TRⁿ_q-λ(Z;p) of the topological Hochschild T-spectrum T(Z) are free abelian for q even, and finite for q odd, and by determining their ranks and orders, respectively.
