The, 3, moment about the mean of the r.v. number of 3-dim. subcubes contained\ in the truth table of a random Boolean function is n 2 n (n - 1) (n - 2) 6 5 4 3 2 (14 n + 24 n + 479 n + 2046 n + 6779 n + 15444 n - 23112)/2415919104 and in Maple notation 1/2415919104*2^n*n*(n-1)*(n-2)*(14*n^6+24*n^5+479*n^4+2046*n^3+6779*n^2+15444*n -23112) hence the scaled, 3, moment is 6 5 4 3 2 / 12 (14 n + 24 n + 479 n + 2046 n + 6779 n + 15444 n - 23112) / ( / 3 2 (4 n + 6 n + 80 n + 363) n 5 4 3 2 1/2 (2 n (4 n - 6 n + 70 n + 135 n - 929 n + 726)) ) and in Maple notation 12*(14*n^6+24*n^5+479*n^4+2046*n^3+6779*n^2+15444*n-23112)/(4*n^3+6*n^2+80*n+ 363)/(2^n*n*(4*n^5-6*n^4+70*n^3+135*n^2-929*n+726))^(1/2) This took, 36.393, seconds. The, 4, moment about the mean of the r.v. number of 3-dim. subcubes contained\ in the truth table of a random Boolean function is #TERMINATED BECAUSE IT TOOK SO LONG
