Formula Help

[Jayzer]

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.

The part after the semicolon makes sense. What is 6&#8721 about? The
& and # and ; are not mathematical operators. Can you provide more
details?

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?
