Hello, I am having a problem with iterators in Mathematica. I have a sequence of integers defined by a[n]. I wish to build a table of integers out of the above such that this table only contains integers of the form a(i)+a(j)+a(k). I tried Table[a[i] + a[j] + a[k], {k, 1, 3}, {j, i, k}, {i, 1, j}] but the iterators do not have appropriate bounds. Any help would be greatly appreciated. Sincerely, Bob.
