Abstract:	In the first of this series of two articles, we studied some geometrical aspects of the Birkhoff polytope, the compact convex set of all n x n doubly stochastic matrices, namely the Chebyshev center, and the Chebyshev radius of the Birkhoff polytope associated with metrics induced by the operator norms from ln^p to ln^p for 1 \leq p \leq infinity. In the present paper, we take another look at those very questions, but for a different family of matrix norms, namely the Schatten p-norms, for 1 \leq p < infinity. While studying these properties, the intrinsic connection to the minimal trace, which naturally appears in the assignment problem, is also established.
