# Enumerate elements of a set built using properties

 0 How can I enumerate all the elements of a set? For example (I'll use latex to describe the desired set) if the set is: $$W = { u_{i}[j], \overline{u}_{i}[j]: 1 \leq i \leq n, 1 \leq j \leq m }$$ asked Oct 18 '11 oscarvarto 41 ● 1 ● 2 ● 3 Mike Hansen 3890 ● 23 ● 46 ● 84 Explain what u_i[j] and \bar{u}_i[j] mean.benjaminfjones (Oct 19 '11)

 0 I don't know what your u_i[j]'s are, but you can do things like the following sage: m = 2; n = 3 sage: [ (i,j) for i in range(m) for j in range(n)] [(0, 0), (0, 1), (0, 2), (1, 0), (1, 1), (1, 2)]  where you would replace (i,j) with the Python/Sage version of your u_i[j]'s. posted Oct 19 '11 Mike Hansen 3890 ● 23 ● 46 ● 84
