n = 3;
list = Array[w, n];
Total /@ Subsets[list]
{0, w[1], w[2], w[3], w[1] + w[2], w[1] + w[3], w[2] + w[3],
w[1] + w[2] + w[3]}

Hi,
I like to create a list of the form:
0,w[1],...,w[n],w[1]+w[2],...,w[1]+w[n],w[2]+w[3],......,w[1]+...+w[n]
for arbitrary n
Is there a neat way to do this?
Cheers,
Dominic
