Given a permutation w, we show that the number of repeated letters in a
reduced decomposition of w is always less than or equal to the number of 321-
and 3412-patterns appearing in w. Moreover, we prove bijectively that the two
quantities are equal if and only if w avoids the ten patterns 4321, 34512,
45123, 35412, 43512, 45132, 45213, 53412, 45312, and 45231.
