Hi, could anyone assist me on a formula for the following mathematical
sum


rs=1-(6∑D²/n³-n)

A friend has asked me to acquire a formula for this sum.

Many Thanks in advance,

James McAuley.


This appears to be a valid formula. It will not work, however, when "n"
is equal to zero. Other than that, what kind of assistance do you need?


Regards.
