Got Sage working again.  It also returns an empty list for r > n.  For r 
negative, Combinations returns an empty list and Permutation gives an 
error.

sage: Combinations(range(4), 6)
Combinations of [0, 1, 2, 3] of length 6
sage: Combinations(range(4), 6).list()
[]
sage: Permutations(range(4), 6).list()
[]
sage: Combinations(range(4), -1).list()
[]
sage: Permutations(range(4), -1).list()
