In my worksheets I have many variables with subscripted/superscripted names like phi_jm1_np1, where the mathematical notation is simple, $\phi_{j-1}^{n+1}$ . Is there a compact notation, or simply a better way, of dealing with subscripts and superscripts using sage?

You might want to combine your variables into a tuple of tuples, or into a dictionary, and write

phi[j-1][n+1]

or

phi[j-1,n+1]
