Given the set a = {x1,2,3,4,5,6}, for X contained in a, define s (x) as the sum of all elements in this subset x, and find the sum of all s (x) ditto

Given the set a = {x1,2,3,4,5,6}, for X contained in a, define s (x) as the sum of all elements in this subset x, and find the sum of all s (x) ditto

That's true
For every k-distant set, there is a 6-k-ary subset, which is not intersected, but the sum of them is a. the sum of S (x) of these two sets is exactly 1 +... + 6 = 21. Since there are 6-ary subsets of 2 to the sixth power and the set logarithm satisfying the previous condition has 32 pairs to the fifth power of 2, the value you want is 21 * 32 = 672
