Given the  Sum product....where the number of sums is variable and
nested...example....which I write logically rather then Mathematically,
easier for me and I think for understanding....

Given...

Sum[ k1=1 to q] Sum[k2=k1 to q] Sum[k3=k2 to q] (k1*k2*k3)

is there a way to write this as ...Product[Sum] ?


I tried   Product[a=1 to 3] Sum[k_subscript_a = k_subscript_(a-1) to q]
but this didnt work...no nesting

What I want is to be able to vary a = 1 to n.....


any ideas?


thanks....jerry blimbaum
