A060130(a(n)) >= 3.


EXAMPLE

27 ("1011" in factorial base) is included as there are three distinct values attained by the difference digit_position  digit_value when computed for its nonzero digits: 41 = 3, 21 = 1 and 11 = 0.
51 ("2011" in factorial base) is included as there are three distinct values attained by the difference digit_position  digit_value when computed for its nonzero digits: 42 = 2, 21 = 1 and 11 = 0.
57 ("2111" in factorial base) is included as there are three distinct values attained by the difference digit_position  digit_value when computed for its nonzero digits: 42 = 31 = 2, 21 = 1 and 11 = 0.
