Ok, you came close! I totally forgot to write what S_j. I didn't know the LaTeX for it.

Here is the equation (which I'll edit in my last post):

[tex]1 = \sum_j \frac{1}{i_j}[/tex]
Ah, that makes more sense! I should have figure that S_j was meant to be summation.

I know |G| is the largest it can ever be. That's just stating the obvious. But I don't see how there will always be an i_j = |G|. In my opinion, if there is an i_j = |G|, then G is centerless.
That's absolutely right.
