Hi everybody !

I have a (silly ?) question: is it possible to find a general formula 
(funtion of n) for the expression:


  n-1      i-2
--------  -------  -   - -   -
 \        \        |i  | | i | n-i-1
  \        \       |   | |   |2
  /        /       |   | |   |
 /        /        |j+2| | j |
--------  -------  -   - -   -
  i=3      j=1


      -   - 
where | n | is the number of combinations of p elements among n.
      | p |
      -   -



thanx in advance
