    Since 4-2-2 contains 2 distinct sets, you have 2*7=14 points from step 1 where your organization is right.
    However, there is a difference between the square of 4 and the sum of the squares of 3 and 1. That's why you shouldn't organize 4-2-2 as 1-1-1 and 3-1-1.
    Test calculates the sum of the squares of 4, 2, and 2 which is 24.
    So the result is 14 + 24 = 38 points.
