Hi Mathematica Friends,

I want to do this:

Limit[(n^2 + (n - 1)^2 + (n - 2)^2 + ... + 1)/n^3, n -> Infinity]

But Mathematica barfs:

     expression cannot be followed by "...".

Searching the help for 'ellipsis' gives me the Unicode 2026 character
(i.e. ...).

How can I get Mathematica to eval this limit?

Thanks,
David.
