The first column forms the totients (A000010). The inverse Moebius transform of each column forms the columns of triangle {n/k*A096799(n,k)}. A generalized Euler transform of the row polynomials of this triangle generates A096651; the row sums of A096651^n form the n-dimensional partitions. %e A096800 G.f.: 1/A096651(x,y) = (1-x)^y*(1-x^2)^[(y+y^2)/2]*(1-x^3)^[(2y+y^3)/3]*(1-x^4)^[(2y+y^2+y^4)/4]*(1-x^5)^[(4y-5y^2+5y^3+y^5)/5]*... %e A096800 Rows begin: %e A096800 [1], %e A096800 [1,1], %e A096800 [2,0,1], %e A096800 [2,1,0,1], %e A096800 [4,-5,5,0,1], %e A096800 [2,2,-5,6,0,1], %e A096800 [6,-28,28,-7,7,0,1], %e A096800 [4,90,-136,49,-8,8,0,1], %e A096800 [6,-738,1082,-432,90,-9,9,0,1], %e A096800 [4,6279,-9525,4075,-969,145,-10,10,0,1], %e A096800 [10,-66594,101915,-44803,11143,-1881,220,-11,11,0,1], %e A096800 [4,816362,-1260268,565988,-144300,25207,-3300,318,-12,12,0,1], %e A096800 [12,-11418459,17738565,-8095100,2105129,-375609,50414,-5382,442,-13,13,0,1],... %Y A096800 Cf.
