@asloob: yup, fixed now, thanks.

Ahh, right—in my quick read, I hadn't thought about the difference between the limit of the finite series and the infinite series. I hadn't meant to imply that the two sides of that = weren't equal; I more meant that the infinite series related to the left side is conditionally convergent and rearrangement would make it not equal to the right side.

Is it the change in form of the series, across the = in the line above (3), that is dependent on the ordering of the series?
