Considering the permutation (0, 5, 3, -1, -4, 2) and the concepts shown in Bergeron 2005, choose the WRONG alternative.
a) The oriented pair (0, -1) has score = 1 and the oriented pair (-1, 2) has score = 0
b) The resulting reduced permutation of the reversal induced by oriented pair (-1, 2) is (0, 3, 2, 1)
c) The permutation contains four oriented pairs: (0, -1), (5, -4), (3, -4) and (-1, 2)
d) The resulting reduced permutation of the reversal induced by oriented pair (-1, 2) is equal to the resulting reduced permutation of the reversal induced by oriented pair (-3, 4). The same operation occurs with oriented pairs (0, -1) and (5, -4).
e) None of the above
